GEODYNE ENERGY INCOME LTD PARTNERSHIP I-F
General        The Geodyne Energy Income Limited Partnership I-D (the "I-D Partnership"), Geodyne  Energy Income  Limited  Partnership  I-E (the "I-E  Partnership"),  and Geodyne  Energy  Income  Limited   Partnership   I-F  (the  "I-F   Partnership") (collectively,  the  "Partnerships")  are limited  partnerships formed under the Oklahoma  Revised Uniform Limited  Partnership Act. Each Partnership is composed of public  investors as limited  partners (the "Limited  Partners")  and Geodyne Resources, Inc. ("Geodyne"), a Delaware corporation, as the general partner. The Partnerships commenced operations on the dates set forth below:                                                Date of                       Partnership           Activation                       -----------       ------------------                            I-D           March 4, 1986                           I-E           September 10, 1986                           I-F           December 16, 1986        Immediately following  activation,  each Partnership invested as a general partner in a separate  Oklahoma general  partnership which actually conducts the Partnerships' production operations.  Geodyne serves as managing partner of such general partnerships.  Unless the context indicates otherwise, all references to any single  Partnership or all of the Partnerships in this Annual Report on Form 10-K ("Annual Report") are references to the Partnership and its related general partnership,  collectively. In addition, unless the context indicates otherwise, all references to the "General  Partner" in this Annual Report are references to Geodyne as the general partner of the Partnerships,  and as the managing partner of the related general partnerships.        The  General  Partner  currently  serves as general  partner of 26 limited partnerships,  including the Partnerships. The General Partner is a wholly-owned subsidiary  of Samson  Investment  Company.  Samson  Investment  Company and its various  corporate  subsidiaries,  including the General  Partner  (collectively "Samson"),  are  primarily  engaged in the  production  and  development  of and exploration  for oil and gas  reserves  and the  acquisition  and  operation  of producing   properties.   At  December  31,  2005,  Samson  owned  interests  in approximately 18,000 oil and gas wells located in 18 states of the United States and the countries of Canada and Venezuela. At December 31, 2005, Samson operated approximately 5,700 oil and gas wells located in 14 states of the United States, as well as Canada and Venezuela.                                          -4-           The Partnerships are currently engaged in the business of owning interests in producing oil and gas properties  located in the  continental  United States. The Partnerships may also engage to a limited extent in development  drilling on producing oil and gas  properties as required for the prudent  management of the Partnerships.        As limited partnerships,  the Partnerships have no officers, directors, or employees. They rely instead on the personnel of the General Partner and Samson. As of February  15,  2006,  Samson  employed  approximately  1,300  persons.  No employees  are  covered by  collective  bargaining  agreements,  and  management believes  that  Samson  provides a sound  employee  relations  environment.  For information  regarding the executive officers of the General Partner,  see "Item 10. Directors and Executive Officers of the General Partner."        The General Partner's and the Partnerships' principal place of business is located at Samson Plaza,  Two West Second Street,  Tulsa,  Oklahoma  74103,  and their telephone number is (918) 583-1791 or (888) 436-3963 [(888) GEODYNE].        Pursuant to the terms of the partnership  agreements for the  Partnerships (the  "Partnership  Agreements"),  the  Partnerships  would have  terminated  on December 31, 1999. However, the Partnership  Agreements provide that the General Partner may extend the term of each  Partnership  for up to five  periods of two years each. The General Partner has extended the terms of the  Partnerships  for the fourth  two-year  extension  period to December 31, 2007.  As of the date of this Annual Report,  the General  Partner has not determined  whether to further extend the term of any Partnership.         Funding        Although  the  Partnership  Agreements  permit each  Partnership  to incur borrowings,   operations   and  expenses  are  currently   funded  out  of  each Partnership's  revenues from oil and gas sales.  The General Partner may, but is not required to, advance funds to a Partnership  for the same purposes for which Partnership borrowings are authorized.         Principal Products Produced and Services Rendered        The  Partnerships'  sole  business  is  the  production  of,  and  related incidental  development  of,  oil and gas.  The  Partnerships  do not  refine or otherwise  process crude oil and  condensate.  The  Partnerships do not hold any patents,  trademarks,  licenses,  or  concessions  and are  not a  party  to any government  contracts.  The  Partnerships  have no  backlog of orders and do not participate in research and development  activities.  The  Partnerships  are not presently encountering shortages of oilfield tubular goods,                                          -5-     compressors,  production  material,  or other  equipment.  However,  substantial increases  in the global  price of steel as well as  increases in the prices for oil and gas supplies and services will further  increase the costs of any future workover, recompletion or drilling activities conducted by the Partnerships.         Competition and Marketing        The primary source of liquidity and Partnership cash  distributions  comes from the net revenues  generated  from the sale of oil and gas produced from the Partnerships'  oil and gas  properties.  The  level of net  revenues  is  highly dependent  upon the total  volumes  of oil and  natural  gas  sold.  Oil and gas reserves are depleting assets and will experience production declines over time, thereby likely  resulting in reduced net revenues.  The level of net revenues is also highly  dependent  upon the prices  received  for oil and gas sales,  which prices  have  historically  been  very  volatile  and  may  continue  to be  so. Additionally,  lower oil and natural gas prices may reduce the amount of oil and gas that is economic to produce and reduce the  Partnerships'  revenues and cash flow.  Various factors beyond the  Partnerships'  control will affect prices for oil and natural gas, such as:        *     Worldwide and domestic supplies of oil and natural gas;       *     The  ability  of  the  members  of  the  Organization  of  Petroleum             Exporting  Countries  ("OPEC") to agree upon and maintain oil prices             and production quotas;       *     Political  instability or armed conflict in oil-producing regions or             around major shipping areas;       *     The level of consumer demand and overall economic activity;       *     The competitiveness of alternative fuels;       *     Weather conditions and the impact of weather-related events;       *     The availability of pipelines for transportation;       *     Domestic and foreign government regulations and taxes; and       *     Market expectations.        It is not  possible to predict the future  direction of oil or natural gas prices or whether the above  discussed  trends  will  remain.  Operating  costs, including General and  Administrative  Expenses,  may not decline over time, may increase or may experience only a gradual decline,  thus adversely affecting net revenues as either  production  or oil and natural  gas prices  decline.  In any particular  period,  net  revenues may also be affected by either the receipt of proceeds from property sales or the incursion of additional costs as a result of well workovers, recompletions, new well drilling, and other events.                                          -6-           Significant Customers        The  following  customers  accounted  for  ten  percent  or  more  of  the Partnerships' oil and gas sales during the year ended December 31, 2005:     Partnership               Customer                     Percentage    -----------    ---------------------------------       ----------         I-D        Chevron U.S.A., Inc.

Management does not expect any of its open access transporters to seek authorization to terminate their transportation services.  Even  if the  services  were  terminated,  management  believes  that alternatives  would  be  available  whereby  the  Partnerships  would be able to continue to market their gas.        The  Partnerships'  principal  customers  for  crude  oil  production  are refiners and other companies  which have pipeline  facilities near the producing properties  of the  Partnerships.  In the  event  pipeline  facilities  are  not conveniently  available to  production  areas,  crude oil is usually  trucked by purchasers to storage facilities.         Oil, Gas, and Environmental Control Regulations        Regulation  of Production  Operations -- The  production of oil and gas is subject to  extensive  federal and state laws and  regulations  governing a wide variety of matters, including the drilling and spacing of wells, allowable rates of  production,  prevention  of  waste  and  pollution,  and  protection  of the environment. In addition to the direct costs borne in complying                                          -7-     with such  regulations,  operations  and  revenues may be impacted to the extent that certain regulations limit oil and gas production to below economic levels.        Regulation  of Sales and  Transportation  of Oil and Gas -- Sales of crude oil and  condensate  are made by the  Partnerships  at market prices and are not subject to price  controls.  The sale of gas may be subject to both  federal and state laws and  regulations.  The provisions of these laws and  regulations  are complex  and  affect  all who  produce,  resell,  transport,  or  purchase  gas, including the  Partnerships.  Although  virtually all of the  Partnerships'  gas production  is not subject to price  regulation,  other  regulations  affect the availability of gas transportation  services and the ability of gas consumers to continue to purchase or use gas at current levels. Accordingly, such regulations may have a material  effect on the  Partnerships'  operations and projections of future oil and gas production and revenues.        Future  Legislation --  Legislation  affecting the oil and gas industry is under  constant  review  for  amendment  or  expansion.  Because  such  laws and regulations  are frequently  amended or  reinterpreted,  management is unable to predict what  additional  energy  legislation  may be proposed or enacted or the future cost and impact of complying with existing or future regulations.        Regulation of the Environment -- The Partnerships'  operations are subject to numerous laws and  regulations  governing the discharge of materials into the environment or otherwise relating to environmental  protection.  Compliance with such  laws  and  regulations,   together  with  any  penalties   resulting  from noncompliance  may  increase  the cost of the  Partnerships'  operations  or may affect  the  Partnerships'   ability  to  timely  complete  existing  or  future activities.  Management  anticipates  that  various  local,  state,  and federal environmental  control  agencies will have an  increasing  impact on oil and gas operations.        Insurance Coverage        The  Partnerships  are  subject  to  all  of  the  risks  inherent  in the exploration for and production of oil and gas,  including  blowouts,  pollution, fires, and other casualties.  The Partnerships maintain insurance coverage as is customary for entities of a similar size engaged in  operations  similar to that of the  Partnerships,  but losses can occur from uninsurable risks or in amounts in excess of existing insurance coverage.  For example,  many types of pollution and  contamination  can exist,  undiscovered,  for long  periods of time and can result in  substantial  environmental  liabilities  which are not  insured.  The occurrence  of an event  which is not fully  covered by  insurance  could have a material adverse effect on the Partnerships'  financial condition and results of operations.                                         -8-
The following factors,  among others, could cause actual results to differ materially  from those  contained  in  forward-looking  statements  made in this report and presented  elsewhere from time to time.  Such factors,  among others, may have a material adverse effect upon the  Partnerships'  business,  financial condition, and results of operations.        The  following  discussion of risk factors  should be read in  conjunction with the  combined  financial  statements  and related  notes  included  herein. Because of these and other  factors,  past financial  performance  should not be considered an indication of future performance.         Oil and Natural Gas Prices Fluctuate Due to a Number of       -------------------------------------------------------       Uncontrollable Factors, and Any Decline Will Adversely       ------------------------------------------------------       Affect the Partnerships' Financial Condition.       ---------------------------------------------        The  Partnerships'  results of  operations  depend  upon the  prices  they receive for their oil and natural gas. We sell most of the Partnerships' oil and natural gas liquids at current  market  prices  rather than through  fixed-price contracts.  Historically, the markets for oil and natural gas have been volatile and are likely to remain so. The prices we receive  depend upon  factors  beyond our control, including:           *  political instability or armed conflict in oil-producing regions;          *  weather conditions;          *  the supply of domestic and foreign oil and natural gas;          *  the ability of members of OPEC to agree upon and maintain prices and             production levels;          *  the level of consumer demand and overall economic activity;          *  worldwide economic demand;          *  the price and availability of alternative fuels;          *  domestic and foreign governmental regulations and taxes;          *  the proximity to and capacity of transportation facilities; and          *  the effect of worldwide energy conservation measures.        Government  regulations,  such as regulation of natural gas transportation and price controls,  can affect product prices in the long term.  These external factors and the  volatile  nature of the energy  markets  make it  difficult  to reliably estimate future prices of oil and natural gas.                                          -9-           Any  decline  in  oil  and  natural  gas  prices  adversely   affects  the Partnerships'  financial  condition.  If the oil and  gas  industry  experiences significant  price declines,  the Partnerships may not be able to maintain their current level of cash  distributions.  See "Item 1 - Business - Competition  and Marketing"  and "Item 7 -  Management's  Discussion  and  Analysis of  Financial Condition and Results of Operations".         Reserve Estimates Depend on Many Assumptions That May Turn       ----------------------------------------------------------       Out to be Inaccurate.  Any Material Inaccuracies in the       -------------------------------------------------------       Partnerships' Reserve Estimates or Underlying Assumptions       ---------------------------------------------------------       Could Cause the Quantities and Net Present Value of Their       ---------------------------------------------------------       Reserves to be Overstated.       --------------------------        Estimating  quantities of proved oil and natural gas reserves is a complex process.  It requires  interpretations  of available  technical data and various assumptions, including assumptions relating to economic factors. Any significant inaccuracies  in these  interpretations  or  assumptions or changes of condition could cause the quantities and net present value of the  Partnerships'  reserves to be overstated.        To prepare  estimates  of  economically  recoverable  oil and  natural gas reserves and future net cash flows,  we analyze many variable  factors,  such as historical  production from the area compared with  production  rates from other producing areas. We also analyze available geological,  geophysical,  production and engineering  data, and the extent,  quality and reliability of this data can vary.  The process  also  involves  economic  assumptions  relating to commodity prices,  production costs,  severance and excise taxes, capital expenditures and workover  and  remedial  costs.  Actual  results  most likely will vary from our estimates.  Any significant  variance could reduce the estimated  quantities and present value of reserves shown in this annual report.        You should not assume that the present value of future net cash flows from the  Partnerships'  proved  reserves  shown in this Annual Report is the current market value of their estimated oil and natural gas reserves. In accordance with Securities  and Exchange  Commission  requirements,  the  Partnerships  base the estimated  discounted future net cash flows from their proved reserves on prices and costs on the date of the  estimate.  Actual  current  and future  prices and costs may differ  materially  from those used in the earlier  net present  value estimate,  and as a result, net present value estimates using current prices and costs may be  significantly  less than the earlier estimate which is provided in this annual  report.  See "Item 2 -  Properties-Proved  Reserves and Net Present Value".                                          -10-             Drilling Oil and Natural Gas Wells is a High-Risk Activity       ----------------------------------------------------------       and Subjects Us to a Variety of Factors That We Cannot       ------------------------------------------------------       Control.       --------        Drilling oil and natural gas wells,  including development wells, involves numerous  risks,  including  the risk that the  Partnerships  may not  encounter commercially  productive oil and natural gas reservoirs.  While the Partnerships do not expend a significant portion of their capital on drilling activities,  to the extent  they do drill wells this can be a  significant  risk factor to them. They may not recover all or any portion of their  investment  in new wells.  The presence  of   unanticipated   pressures  or   irregularities   in   formations, miscalculations  or  accidents  may  cause  their  drilling   activities  to  be unsuccessful  and  result  in a total  loss  of  investment.  Further,  drilling operations  may be  curtailed,  delayed or  canceled as a result of a variety of factors, including:           *  unexpected drilling conditions;          *  title problems;          *  restricted access to land for drilling or laying pipeline;          *  pressure or irregularities in formations;          *  equipment failure or accidents;          *  adverse weather conditions; and          *  costs of, or shortages  or delays in the  availability of,  drilling             rigs, tubular materials and equipment.         The Marketability of the Partnerships' Production is       ----------------------------------------------------       Dependent upon Transportation and Processing Facilities Over       ------------------------------------------------------------       Which We Have No Control.       -------------------------        The marketability of the Partnerships' production depends in part upon the availability, proximity and capacity of pipelines, natural gas gathering systems and processing  facilities.  Any significant  change in market factors affecting these  infrastructure  facilities  could harm their business.  The  Partnerships deliver oil and natural gas through gathering systems and pipelines that they do not  own.  These  facilities  may  be  temporarily  unavailable  due  to  market conditions or mechanical reasons, or may not be available to us in the future.                                           -11-           Reliance on Third Party Operators       ---------------------------------        A  substantial  portion of the  Partnerships'  properties  are operated by third  parties.   The  Partnerships  have  little,  if  any,  control  over  the operational  decisions and costs associated with these properties.  In addition, the  Partnerships  are totally  reliant on the third party  operators'  internal controls associated with the operator's accounting for revenues and expenses.         No Market for Units       -------------------        The Partnerships'  Units are not listed on any exchange or national market system, and there is no established public trading market for the Units. You may only sell your Units via (i) the General Partner's annual Repurchase Offer; (ii) transfers  facilitated  by secondary  trading firms and matching  services;  and (iii)  occasional  "4.9% tender offers" which are made for the Units.  Secondary market   activity   for  the  Units  has  been  limited  and  varies  among  the Partnerships.  See  "Item 5 - Market  for  Units  and  Related  Limited  Partner Matters".         Limited Life       ------------        The  Partnerships  are  currently  scheduled  to terminate on December 31, 2007.  Even  if  the  General   Partner   exercises  its  right  to  extend  the Partnerships'  terms for one additional  two-year period,  the Partnerships will terminate no later than December 31, 2009. Upon  termination  the  Partnerships' assets will be sold.  There is no assurance  that the market for the sale of the Partnerships' assets will be favorable at such time.         The Partnerships are Subject to Complex Federal, State and       ----------------------------------------------------------       Local Laws and Regulations that Could Adversely Affect Their       ------------------------------------------------------------       Business       ---------        Extensive federal,  state and local regulation of the oil and gas industry significantly  affects the  Partnerships'  operations.  In particular,  they are subject to stringent environmental  regulations.  These regulations increase the costs of planning, designing, drilling, installing, operating and abandoning oil and natural gas wells and other related facilities. These regulations may become more demanding in the future. Matters subject to regulation include:                                          -12-              *  discharge permits for drilling operations;          *  drilling bonds;          *  spacing of wells;          *  unitization and pooling of properties;          *  environmental protection;          *  reports concerning operations; and          *  taxation.        Under these laws and regulations, the Partnerships could be liable for:           *  personal injuries;          *  property damage;          *  oil spills;          *  discharge of hazardous materials;          *  reclamation costs;          *  remediation and clean-up costs; and          *  other environmental damages.        While the Partnerships maintain insurance coverage customary for companies similar to their size and operations, losses can occur from uninsurable risks or in amounts in excess of existing insurance coverage. See "Item 1 - Business".         Conflicts of Interest       ---------------------        Direct and indirect  conflicts of interests  exist among the  Partnerships and among a Partnership and the General Partner and its affiliates.  The General Partner and its  affiliates  engage in many aspects of the oil and gas business, including  acting as a general  partner  of a number of  affiliated  oil and gas limited  partnerships.  The  General  Partner and its  affiliates  may engage in transactions  with a Partnership,  and  Partnerships  will frequently  engage in transactions with other oil and gas limited partnerships.  These conflicts could relate  to  the  sale  of oil  and  gas  properties,  the  determination  of the Partnerships'  Repurchase  Prices,  and the determination of whether to continue the Partnerships past their scheduled termination date of December 31, 2007. See "Item 13 - Certain Relationships and Related Transactions".         Payments to the General Partner       -------------------------------        The General Partner receives reimbursements for General and Administrative Expenses.  The  General  Partner  also  receives  a share  of  Partnership  cash distributions.  See "Item 11 - Executive  Compensation"  and "Item 8 - Financial Statements and Supplementary Data".                                           -13-           Financial Capability of General Partner       ---------------------------------------        The General Partner has limited  financial  resources.  Contingencies  may arise which will require  funding beyond its financial  resources.  Even if such financial  resources are available,  the General Partner is not required to lend money or to fund any financial obligations of the Partnerships.         Liability and Indemnification of General Partner and Related       ------------------------------------------------------------       Parties       -------        Although the General Partner  generally will be liable for the obligations of the Partnerships, the Partnership Agreements provide that the claims of third parties will be initially  satisfied from  Partnership  assets.  The Partnership Agreements also provide,  subject to certain  conditions,  that the Partnerships will reimburse  (i.e.  "indemnify")  the General  Partner and its affiliates for certain costs, claims and expenses.

Regardless  of a  well's  oil  or gas       designation, it may produce oil, gas, or both oil and gas. (2)   As used in this Annual  Report,  "gross  well" refers to a well in which a       working interest is owned;  accordingly,  the number of gross wells is the       total number of wells in which a working interest is owned. (3)   As  used  in this  Annual  Report,  "net  well"  refers  to the sum of the       fractional  working  interests  owned in gross wells.  For example,  a 15%       working interest in a well represents one gross well, but 0.15 net well.

As used in the following tables, direct operating expenses include lease operating  expenses and production  taxes. In addition,  gas production is converted to oil equivalents at the rate of six Mcf per barrel, representing the estimated  relative energy content of gas and oil, which rate is not necessarily indicative of the relationship of oil and gas prices.  The respective  prices of oil and gas are  affected  by market and other  factors in  addition to relative energy content.

forth each Partnership's estimated proved oil and gas reserves  and net present  value  therefrom  as of December  31,  2005.  The schedule  of  quantities  of proved oil and gas  reserves  was  prepared  by the General  Partner in accordance  with the rules  prescribed by the Securities and Exchange  Commission (the "SEC").  Certain  reserve  information was reviewed by Ryder Scott Company,  L.P. ("Ryder Scott"), an independent petroleum engineering firm. As used throughout this Annual Report,  "proved  reserves" refers to those estimated  quantities of crude oil, gas, and gas liquids  which  geological  and engineering  data  demonstrate  with  reasonable  certainty to be recoverable in future  years from known oil and gas  reservoirs  under  existing  economic  and operating conditions.                                           -19-           Net present  value  represents  estimated  future gross cash flow from the production and sale of proved reserves,  net of estimated oil and gas production costs (including production taxes, ad valorem taxes, and operating expenses) and estimated  future  development  costs,  discounted at 10% per annum. Net present value  attributable to the  Partnerships'  proved reserves was calculated on the basis of current  costs and prices at December  31,  2005.  Such prices were not escalated  except in  certain  circumstances  where  escalations  were fixed and readily determinable in accordance with applicable contract provisions.  Oil and gas  prices at  December  31,  2005  ($61.06  per  barrel  and  $10.08  per Mcf, respectively)  were  substantially  higher than the prices in effect on December 31, 2004 ($43.36 per barrel and $6.02 per Mcf,  respectively).  This increase in oil  and  gas  prices  has  caused  the  estimates  of  remaining   economically recoverable reserves, as well as the values placed on said reserves, at December 31, 2005 to be higher than such  estimates and values at December 31, 2004.  The prices  used  in  calculating   the  net  present  value   attributable  to  the Partnerships'  proved reserves do not necessarily  reflect market prices for oil and gas  production  subsequent to December 31, 2005. In fact, as of the date of this Annual  Report,  natural gas prices have  declined  significantly  from the December  31,  2005  price.  There can be no  assurance  that the prices used in calculating  the net  present  value of the  Partnerships'  proved  reserves  at December 31, 2005 will actually be realized for such production.        The process of  estimating  oil and gas  reserves  is  complex,  requiring significant  subjective  decisions in the  evaluation  of available  geological, engineering,  and  economic  data  for  each  reservoir.  The  data  for a given reservoir may change substantially over time as a result of, among other things, additional development activity, production history, and viability of production under varying economic conditions;  consequently, it is reasonably possible that material  revisions to existing reserve  estimates may occur in the near future. Although  every  reasonable  effort has been made to ensure  that these  reserve estimates represent the most accurate assessment  possible,  the significance of the  subjective  decisions  required and variances in available data for various reservoirs  make these  estimates  generally  less precise than other  estimates presented in connection with financial statement disclosures.                                            -20-                                     Proved Reserves and                                Net Present Values                               From Proved Reserves                            As of December 31, 2005(1)  I-D Partnership: - ---------------    Estimated proved reserves:      Gas (Mcf)                                                     1,559,316      Oil and liquids (Bbls)                                           71,529     Net present value (discounted at 10% per annum)               $ 7,249,132  I-E Partnership: - ---------------    Estimated proved reserves:      Gas (Mcf)                                                     8,258,668      Oil and liquids (Bbls)                                          531,483     Net present value (discounted at 10% per annum)               $41,189,324  I-F Partnership: - ---------------    Estimated proved reserves:      Gas (Mcf)                                                     2,453,345      Oil and liquids (Bbls)                                          250,616     Net present value (discounted at 10% per annum)               $13,999,885 - ----------  (1)   Includes  certain gas  balancing  adjustments  which cause the gas volumes       and net present values to differ from the reserve reports  prepared by the       General Partner and reviewed by Ryder Scott.

Record title to all of the Partnerships'  properties is held by either the Partnerships or Geodyne Nominee Corporation,  an affiliate of the General Partner.        Title to the  Partnerships'  properties  is subject to customary  royalty, overriding  royalty,   carried,   working,   and  other  similar  interests  and contractual  arrangements  customary in the oil and gas  industry,  to liens for current taxes not yet due, and to other  encumbrances.  Management believes that such burdens do not materially detract from the value of such properties or from the Partnerships' interest therein or materially interfere with their use in the operation of the Partnerships' business.
To the knowledge of the General  Partner,  neither the General Partner nor the Partnerships or their properties are subject to any litigation,  the results of which  would  have a  material  effect on the  Partnerships'  or the  General Partner's financial condition or operations.
There were no matters  submitted to a vote of the Limited  Partners of any Partnership during 2005.                                        PART II.
As of March 1, 2006, the number of Units  outstanding  and the approximate number of Limited Partners of record in the Partnerships were as follows:                                                   Number of                                  Number of        Limited                Partnership         Units          Partners                -----------       ---------       ---------                    I-D             7,195              578                    I-E            41,839            2,196                    I-F            14,321              674                                          -24-           Units were initially sold for a price of $1,000.  The Units are not traded on any  exchange  and there is no public  trading  market for them.  The General Partner is aware of certain transfers of Units between unrelated  parties,  some of which are facilitated by secondary  trading firms and matching  services.  In addition,  as further  described  below, the General Partner is aware of certain "4.9% tender  offers"  which have been made for the Units.  The General  Partner believes  that the  transfers  between  unrelated  parties have been limited and sporadic  in number  and  volume.  Other  than  trades  facilitated  by  certain secondary trading firms and matching  services,  no organized trading market for Units  exists  and none is  expected  to  develop.  Due to the  nature  of these transactions, the General Partner has no verifiable information regarding prices at which Units have been  transferred.  Further,  a transferee  may not become a substitute Limited Partner without the consent of the General Partner.        Pursuant to the terms of the Partnership  Agreements,  the General Partner is  obligated  to  annually  issue a  repurchase  offer  which  is  based on the estimated future net revenues from the Partnerships'  reserves and is calculated pursuant to the terms of the Partnership  Agreements.  Such repurchase  offer is recalculated  monthly  in order to reflect  cash  distributions  to the  Limited Partners and  extraordinary  events.  The following table sets forth the General Partner's repurchase offer per Unit as of the periods indicated.  For purpose of this Annual Report,  a Unit  represents an initial  subscription  of $1,000 to a Partnership.

The General  Partner  does not know the terms of these offers or the prices received by the Limited Partners who accepted these offers.         Cash Distributions        Cash  distributions  are primarily  dependent  upon a  Partnership's  cash receipts from the sale of oil and gas  production and cash  requirements  of the Partnership.  Distributable cash is determined by the General Partner at the end of each calendar  quarter and distributed to the Limited Partners within 45 days after the end of the quarter.  Distributions are restricted to cash on hand less amounts  required  to be  retained  out of such cash as  determined  in the sole judgment of the General  Partner to pay costs,  expenses,  or other  Partnership obligations whether accrued or anticipated to accrue. In certain instances,  the General  Partner may not distribute the full amount of cash receipts which might otherwise be available  for  distribution  in an effort to equalize or stabilize the amounts of quarterly  distributions.  Any available  amounts not distributed are  invested  and the  interest  or income  thereon is for the  accounts of the Limited Partners.        The  following  is a summary  of cash  distributions  paid to the  Limited Partners during 2004 and 2005 and the first quarter of 2006:                                          -26-                                    Cash Distributions                               ------------------                                      2004                    -----------------------------------------                     1st         2nd        3rd         4th       P/ship        Qtr.

Use of Forward-Looking Statements and Estimates        This Annual Report contains certain forward-looking  statements. The words "anticipate,"  "believe,"  "expect,"  "plan," "intend,"  "estimate,"  "project," "could," "may," and similar expressions are intended to identify forward-looking statements.  Such statements reflect  management's current views with respect to future  events and  financial  performance.  This Annual  Report  also  includes certain information which is, or is based upon, estimates and assumptions.  Such estimates and assumptions  are  management's  efforts to accurately  reflect the condition and operation of the Partnerships.        Use of  forward-looking  statements and estimates and assumptions  involve risks and uncertainties which include, but are not limited to, the volatility of oil and gas prices, the uncertainty of reserve  information,  the operating risk associated with oil and gas properties  (including the risk of personal  injury, death, property damage, damage to the well or producing reservoir, environmental contamination,  and other  operating  risks),  the  prospect of changing tax and regulatory laws, the availability and capacity of processing and  transportation facilities,  the  accuracy of third party  payments  and  billings,  the general economic  climate,  the supply and price of foreign  imports of oil and gas, the level of consumer product demand,  and the price and availability of alternative fuels.  Should  one or more of these  risks  or  uncertainties  occur or  should estimates or  underlying  assumptions  prove  incorrect,  actual  conditions  or results  may vary  materially  and  adversely  from those  stated,  anticipated, believed, estimated, or otherwise indicated.         General Discussion        The following  general  discussion  should be read in conjunction with the analysis  of  results  of  operations  provided  below.  The  primary  source of liquidity  and  Partnership  cash  distributions  comes  from  the net  revenues generated from the sale of oil and gas produced from the  Partnerships'  oil and gas  properties.  The level of net revenues is highly  dependent upon the prices received  for oil and gas  sales,  which  prices  have  historically  been  very volatile  and may  continue  to be so.  Additionally,  lower oil and natural gas prices  may reduce the  amount of oil and gas that is  economic  to produce  and reduce the  Partnerships'  revenues and cash flow.  Various  factors  beyond the Partnerships' control will affect prices for oil and natural gas, such as:                                          -31-            *     Worldwide and domestic supplies of oil and natural gas;       *     The  ability of the members of OPEC to agree upon and  maintain  oil             prices and production quotas;       *     Political  instability or armed conflict in oil-producing regions or             around major shipping areas;       *     The level of consumer demand and overall economic activity;       *     The competitiveness of alternative fuels;       *     Weather conditions and the impact of weather-related events;       *     The availability of pipelines for transportation;       *     Domestic and foreign government regulations and taxes; and       *     Market expectations.        It is not  possible to predict the future  direction of oil or natural gas prices or whether the above  discussed  trends  will  remain.  Operating  costs, including General and  Administrative  Expenses,  may not decline over time, may increase, or may experience only a gradual decline, thus adversely affecting net revenues as either  production  or oil and natural  gas prices  decline.  In any particular  period,  net  revenues may also be affected by either the receipt of proceeds from property sales or the incursion of additional costs as a result of well workovers, recompletions, new well drilling, and other events.        In addition to pricing, the level of net revenues is also highly dependent upon the total  volumes of oil and natural gas sold.  Oil and gas  reserves  are depleting  assets and will  experience  production  declines over time,  thereby likely  resulting  in  reduced  net  revenues.  Despite  this  general  trend of declining production,  several factors can cause the volumes of oil and gas sold to increase,  remain  relatively  constant,  or decrease at an even greater rate over a given period. These factors include, but are not limited to:        *     geophysical conditions which cause an acceleration of the decline in             production,       *     the  shutting  in of wells (or the  opening  of  previously  shut-in             wells) due to low oil and gas  prices (or high oil and gas  prices),             mechanical  difficulties,  loss of a market  or  transportation,  or             performance of workovers,  recompletions, or other operations in the             well,       *     prior period volume  adjustments  (either positive or negative) made             by operators of the properties,       *     adjustments in ownership or rights to production in accordance  with             agreements governing the operation or ownership of the well (such as             adjustments that occur at payout or due to gas balancing), and       *     completion of enhanced recovery  projects which increase  production             for the well.  Many of these  factors  are very  significant  as related to a single well or as related to many wells over a short period of time.                                          -32-     However,  due to the large  number  of wells  owned by the  Partnerships,  these factors  are  generally  not  material  as  compared  to the  normal  decline in production experienced on all remaining wells.         Results of Operations        An  analysis  of the  change  in net oil and gas  operations  (oil and gas sales,  less lease operating  expenses and production taxes) is presented in the tables  following  "Results  of  Operations"  under the heading  "Average  Sales Prices,  Production  Volumes,  and Average  Production  Costs."  Following  is a discussion  of each  Partnership's  results  of  operations  for the year  ended December  31, 2005 as compared to the year ended  December  31, 2004 and for the year ended December 31, 2004 as compared to the year ended December 31, 2003.                                   I-D Partnership                                 ---------------                       Year Ended December 31, 2005 Compared                         to Year Ended December 31, 2004                      -------------------------------------        Total oil and gas sales increased  $318,000 (34.1%) in 2005 as compared to 2004.  Of this  increase  $53,000 and  $276,000,  respectively,  were related to increases  in the  average  prices of oil and gas  sold.  These  increases  were partially  offset by a decrease  of $15,000  related to a decrease in volumes of gas sold.  Volumes of oil sold increased 105 barrels,  while volumes of gas sold decreased 2,801 Mcf in 2005 as compared to 2004.        The decrease in volumes of gas sold was primarily  due to normal  declines in  production.  This  decrease  was  partially  offset  by (i)  the  successful completion  of several new wells  during  late 2004 and early to mid 2005,  (ii) positive prior period volume  adjustments made by the operators on several wells during 2005,  and (iii) the first  receipt of revenues on one  significant  well during early 2005.        Average  oil and gas prices  increased  to $54.82 per barrel and $7.29 per Mcf,  respectively,   in  2005  from  $40.06  per  barrel  and  $5.38  per  Mcf, respectively, in 2004.        Oil and gas production  expenses  (including lease operating  expenses and production  taxes)  increased  $47,000 (27.7%) in 2005 as compared to 2004. This increase was  primarily due to (i) an increase in  production  taxes  associated with the  increase  in oil and gas  sales,  (ii)  positive  prior  period  lease operating  expense  adjustments  made on several  wells during  2005,  and (iii) workover expenses incurred on several other wells during 2005. As a                                          -33-     percentage of oil and gas sales,  these expenses decreased to 17.4% in 2005 from 18.3% in 2004.        Depreciation,   depletion,  and  amortization  ("DD&A")  of  oil  and  gas properties  increased  $8,000  (25.2%)  in 2005 as  compared  to  2004.  Of this increase (i) $10,000 was due to the depletion of additional capitalized costs of oil and gas properties as a result of the upward revision in the estimate of the asset  retirement  obligations,  of which $8,000 was related to previously fully depleted wells,  and (ii) $1,000 was due to accretion of these  additional asset retirement  obligations.  This  increase was also due to two  significant  wells being fully depleted  during 2005 due to the lack of remaining  reserves.  These increases were partially offset by (i) several wells being fully depleted during 2004 due to the lack of  remaining  reserves  and (ii) upward  revisions  in the estimates  of  remaining  oil and gas reserves  since  December  31, 2004.  As a percentage  of oil and gas sales,  this  expense  decreased to 3.3% in 2005 from 3.6% in 2004.        General and  administrative  expenses  increased  $7,000 (6.6%) in 2005 as compared to 2004. As a percentage of oil and gas sales, these expenses decreased to 9.1% in 2005 from 11.4% in 2004, primarily due to the increase in oil and gas sales.        The Limited Partners have received cash distributions through December 31, 2005 totaling $17,843,175 or 248.00% of Limited Partners' capital contributions.                         Year Ended December 31, 2004 Compared                         to Year Ended December 31, 2003                      -------------------------------------        Total oil and gas sales  decreased  $76,000  (7.6%) in 2004 as compared to 2003.  Of this  decrease  $8,000 and  $164,000,  respectively,  were  related to decreases in volumes of oil and gas sold.  These decreases were partially offset by increases of $39,000 and $57,000,  respectively,  related to increases in the average  prices of oil and gas sold.  Volumes of oil and gas sold  decreased 294 barrels and 32,913 Mcf, respectively,  in 2004 as compared to 2003. The decrease in volumes of gas sold was  primarily  due to (i) normal  declines in production and (ii) the shutting-in of one significant well during 2004 in order to perform a workover.        Average  oil and gas prices  increased  to $40.06 per barrel and $5.38 per Mcf,  respectively,   in  2004  from  $28.87  per  barrel  and  $4.99  per  Mcf, respectively, in 2003.        Oil and gas production  expenses  (including lease operating  expenses and production  taxes)  decreased  $14,000  (7.6%) in 2004 as compared to 2003. As a percentage of oil and gas sales,  these expenses  remained  constant at 18.3% in 2004 and 2003.                                          -34-            DD&A  of oil and  gas  properties  decreased  $39,000  (54.1%)  in 2004 as compared to 2003.  This decrease was primarily due to (i) one  significant  well being fully depleted in 2003 due to the lack of remaining  reserves and (ii) the decreases in volumes of oil and gas sold.  These decreases were partially offset by several other wells being fully depleted in 2004 due to the lack of remaining reserves.  As a percentage of oil and gas sales,  this expense decreased to 3.6% in 2004 from 7.2% in 2003,  primarily due to the dollar  decrease in DD&A of oil and gas properties.        General and administrative  expenses remained  relatively constant in 2004 and 2003.  As a percentage  of oil and gas sales,  these  expenses  increased to 11.4% in 2004 from 10.5% in 2003.                                    I-E Partnership                                 ---------------                       Year Ended December 31, 2005 Compared                         to Year Ended December 31, 2004                      -------------------------------------        Total oil and gas sales increased  $1,890,000  (31.8%) in 2005 as compared to 2004. Of this increase $641,000 and $1,605,000, respectively, were related to increases  in the  average  prices of oil and gas  sold.  These  increases  were partially offset by decreases of $187,000 and $169,000, respectively, related to decreases in volumes of oil and gas sold.  Volumes of oil and gas sold decreased 4,982 barrels and 32,222 Mcf, respectively, in 2005 as compared to 2004.        The  decrease  in  volumes  of oil sold was  primarily  due to (i)  normal declines in production and (ii) a negative prior period volume  adjustment  made by the operator on one significant  well during 2005. The decrease in volumes of gas sold was primarily due to normal  declines in production.  This decrease was partially offset by (i) an increase in production on several wells following the successful  workover  of those wells  during mid 2004 and early  2005,  (ii) the successful  completion  of several  new wells  during late 2004 and early to mid 2005, and (iii) positive prior period volume  adjustments  made by the operators on several other wells during 2005.        Average  oil and gas prices  increased  to $53.74 per barrel and $7.28 per Mcf,  respectively,   in  2005  from  $37.56  per  barrel  and  $5.23  per  Mcf, respectively, in 2004.        Oil and gas production  expenses  (including lease operating  expenses and production  taxes) increased  $197,000 (14.0%) in 2005 as compared to 2004. This increase was  primarily due to (i) workover  expenses  incurred on several wells during 2005, (ii) an increase in production  taxes  associated with the increase in oil                                          -35-     and  gas  sales,  and  (iii)  positive  prior  period  lease  operating  expense adjustments  made on several  other wells  during  2005.  These  increases  were partially offset by (i) a reversal during 2005 of $89,000 of a charge previously accrued for a judgment  and (ii)  workover  expenses  incurred on several  wells during 2004. As a percentage of oil and gas sales,  these expenses  decreased to 20.4% in 2005 from 23.6% in 2004. This percentage  decrease was primarily due to the increase in oil and gas sales.        Depreciation,   depletion,  and  amortization  ("DD&A")  of  oil  and  gas properties  increased  $174,000  (89.2%) in 2005 as  compared  to 2004.  Of this increase (i) $162,000 was due to the depletion of additional  capitalized  costs of oil and gas properties as a result of the upward  revision in the estimate of the asset  retirement  obligations,  of which $128,000 was related to previously fully depleted wells,  and (ii) $21,000 was due to accretion of these additional asset  retirement  obligations.  This  increase was also due to two  significant wells being fully  depleted  during 2005 due to the lack of remaining  reserves. These increases were partially  offset by (i) several wells being fully depleted during 2004 due to the lack of remaining  reserves and (ii) upward  revisions in the  estimates of remaining oil and gas reserves  since  December 31, 2004. As a percentage  of oil and gas sales,  this  expense  increased to 4.7% in 2005 from 3.3%  in  2004,  primarily  due to the  dollar  increase  in DD&A of oil and gas properties.        General and administrative  expenses remained  relatively constant in 2005 and 2004. As a percentage of oil and gas sales, these expenses decreased to 6.5% in 2005 from 8.5% in 2004, primarily due to the increase in oil and gas sales.        The Limited Partners have received cash distributions through December 31, 2005 totaling $74,942,552 or 179.12% of Limited Partners' capital contributions.                        Year Ended December 31, 2004 Compared                         to Year Ended December 31, 2003                      -------------------------------------        Total oil and gas sales  decreased  $329,000 (5.2%) in 2004 as compared to 2003. Of this  decrease  $242,000 and  $810,000,  respectively,  were related to decreases in volumes of oil and gas sold.  These decreases were partially offset by increases of $446,000 and $277,000, respectively, related to increases in the average prices of oil and gas sold.  Volumes of oil and gas sold decreased 8,766 barrels and 165,627 Mcf, respectively, in 2004 as compared to 2003.        The  decrease  in  volumes  of oil sold was  primarily  due to (i)  normal declines in production and (ii) a positive prior period volume  adjustment  made by the operator on one significant  well during 2003. The decrease in volumes of gas sold was primarily                                          -36-     due to (i)  normal  declines  in  production  and  (ii) the  shutting-in  of one significant well during 2004 in order to perform a workover.        Average  oil and gas prices  increased  to $37.56 per barrel and $5.23 per Mcf,  respectively,   in  2004  from  $27.57  per  barrel  and  $4.89  per  Mcf, respectively, in 2003.        Oil and gas production  expenses  (including lease operating  expenses and production taxes) remained  relatively  constant in 2004 and 2003. A decrease in lease operating expenses associated with the decreases in volumes of oil and gas sold was substantially offset by (i) workover expenses incurred on several wells during  2004 and (ii)  repair  and  maintenance  expenses  incurred  on  another significant  well  during  2004.  As a  percentage  of oil and gas sales,  these expenses increased to 23.6% in 2004 from 22.5% in 2003.        DD&A of oil and  gas  properties  decreased  $291,000  (59.8%)  in 2004 as compared to 2003.  This decrease was primarily due to (i) one  significant  well being fully depleted in 2003 due to the lack of remaining  reserves and (ii) the decreases in volumes of oil and gas sold.  These decreases were partially offset by several other wells being fully depleted in 2004 due to the lack of remaining reserves.  As a percentage of oil and gas sales,  this expense decreased to 3.3% in 2004 from 7.7% in 2003,  primarily due to the dollar  decrease in DD&A of oil and gas properties.        General and administrative  expenses remained  relatively constant in 2004 and 2003. As a percentage of oil and gas sales, these expenses increased to 8.5% in 2004 from 8.2% in 2003.

Of this increase (i) $283,000 and $437,000,  respectively, were related to increases in the average prices of oil and gas sold and (ii) $41,000 was related to an increase in volumes of gas sold.  These increases were partially offset by a decrease of $68,000  related to a decrease in volumes of oil sold.  Volumes of oil sold decreased 1,805 barrels,  while volumes of gas sold increased 7,537 Mcf in 2005 as compared to 2004.        The  decrease  in  volumes  of oil sold was  primarily  due to (i)  normal declines in production and (ii) a negative prior period volume  adjustment  made by the operator on one significant  well during 2005. The increase in volumes of gas sold was primarily                                          -37-     due to (i) an increase in  production  on two  significant  wells  following the successful  workover  of those wells  during mid 2004 and early  2005,  (ii) the successful  completion  of several  new wells  during late 2004 and early to mid 2005, and (iii) positive prior period volume  adjustments  made by the operators on several wells during 2005.  These  increases were partially  offset by normal declines in production.        Average  oil and gas prices  increased  to $53.38 per barrel and $7.33 per Mcf,  respectively,   in  2005  from  $37.79  per  barrel  and  $5.48  per  Mcf, respectively, in 2004.        Oil and gas production  expenses  (including lease operating  expenses and production  taxes)  increased  $13,000 (2.3%) in 2005 as compared to 2004.  This increase was  primarily due to (i) workover  expenses  incurred on several wells during 2005, (ii) an increase in production  taxes  associated with the increase in oil and gas sales,  and (iii) positive prior period lease  operating  expense adjustments  made on several  other wells  during  2005.  These  increases  were partially offset by (i) a reversal during 2005 of $62,000 of a charge previously accrued for a judgment  and (ii)  workover  expenses  incurred on several  wells during 2004. As a percentage of oil and gas sales,  these expenses  decreased to 21.8% in 2005 from 28.6% in 2004. This percentage  decrease was primarily due to the increase in oil and gas sales.        Depreciation,   depletion,  and  amortization  ("DD&A")  of  oil  and  gas properties  increased  $115,000  (168.3%) in 2005 as  compared to 2004.  Of this increase (i) $95,000 was due to the depletion of additional capitalized costs of oil and gas properties as a result of the upward revision in the estimate of the asset retirement  obligations,  of which $81,000 was related to previously fully depleted wells,  and (ii) $11,000 was due to accretion of these additional asset retirement  obligations.   These  increases  were  partially  offset  by  upward revisions in the estimates of remaining oil and gas reserves  since December 31, 2004.  As a percentage of oil and gas sales,  this expense  increased to 6.8% in 2005 from 3.4% in 2004,  primarily due to the dollar increase in DD&A of oil and gas properties.        General and  administrative  expenses  increased  $7,000 (3.5%) in 2005 as compared to 2004. As a percentage of oil and gas sales, these expenses decreased to 7.2% in 2005 from 9.4% in 2004,  primarily due to the increase in oil and gas sales.        The Limited Partners have received cash distributions through December 31, 2005 totaling $23,614,664 or 164.90% of Limited Partners' capital contributions.                                          -38-                          Year Ended December 31, 2004 Compared                         to Year Ended December 31, 2003                      -------------------------------------        Total oil and gas sales  increased  $41,000  (2.1%) in 2004 as compared to 2003.  Of this  increase  $200,000  and $92,000,  respectively,  were related to increases  in the  average  prices of oil and gas  sold.  These  increases  were partially offset by decreases of $111,000 and $140,000, respectively, related to decreases in volumes of oil and gas sold.  Volumes of oil and gas sold decreased 4,007 barrels and 27,549 Mcf, respectively, in 2004 as compared to 2003.        The  decrease  in  volumes  of oil sold was  primarily  due to (i)  normal declines in production and (ii) positive prior period volume adjustments made by the operators on several wells during 2003.  The decrease in volumes of gas sold was primarily due to normal declines in production.  This decrease was partially offset by a negative prior period volume  adjustment made by the operator on one significant well during 2003.        Average  oil and gas prices  increased  to $37.79 per barrel and $5.48 per Mcf,  respectively,   in  2004  from  $27.79  per  barrel  and  $5.08  per  Mcf, respectively, in 2003.        Oil and gas production  expenses  (including lease operating  expenses and production  taxes)  increased  $34,000 (6.2%) in 2004 as compared to 2003.  This increase was  primarily due to (i) workover  expenses  incurred on several wells during  2004 and (ii)  repair  and  maintenance  expenses  incurred  on  another significant  well  during  2004.  These  increases  were  partially  offset by a decrease in lease operating expenses associated with the decreases in volumes of oil and gas sold. As a percentage of oil and gas sales, these expenses increased to 28.6% in 2004 from 27.5% in 2003.        DD&A  of oil and  gas  properties  decreased  $13,000  (15.8%)  in 2004 as compared to 2003.  This  decrease  was  primarily  due to (i) the  decreases  in volumes  of oil and gas sold  and (ii) an  increase  in  depletable  oil and gas properties in 2003 primarily due to  recompletion  activities on one significant well.  As a percentage of oil and gas sales,  this expense  decreased to 3.4% in 2004 from 4.1% in 2003,  primarily due to the dollar decrease in DD&A of oil and gas properties.        General and administrative  expenses remained  relatively constant in 2004 and 2003. As a percentage of oil and gas sales, these expenses decreased to 9.4% in 2004 from 9.6% in 2003.                                          -39-           Average Sales Prices, Production Volumes and Average Production Costs        The following  tables are  comparisons  of the annual  average oil and gas sales prices,  production volumes, and average production costs (lease operating expenses and production  taxes) per barrel of oil equivalent  (one barrel of oil or six Mcf of gas) for 2005, 2004, and 2003.                                2005 Compared to 2004                               ---------------------                                Average Sales Prices - -------------------------------------------------------------------------- P/ship                 2005                  2004             % Change - ------          ------------------    ------------------   ---------------                   Oil        Gas        Oil        Gas                 ($/Bbl)    ($/Mcf)    ($/Bbl)    ($/Mcf)    Oil       Gas                 -------    -------    -------    -------   -----     -----   I-D            $54.82      $7.29     $40.06      $5.38      37%      36%  I-E             53.74       7.28      37.56       5.23      43%      39%  I-F             53.38       7.33      37.79       5.48      41%      34%                                   Production Volumes - --------------------------------------------------------------------------  P/ship                2005                   2004            % Change - --------        ------------------    ------------------   ---------------                  Oil         Gas       Oil        Gas       Oil       Gas                 (Bbls)      (Mcf)     (Bbls)     (Mcf)     (Bbls)    (Mcf)                 ------     -------    ------     -------   ------    -----    I-D            3,575     144,538     3,470     147,339      3%      (2%)   I-E           39,629     784,104    44,611     816,326    (11%)     (4%)   I-F           18,138     236,641    19,943     229,104    ( 9%)      3%                             Average Production Costs per                            Barrel of Oil Equivalent                     --------------------------------------                     P/ship     2005      2004     % Change                     ------    ------    -----     --------                       I-D      $ 7.88    $6.09        29%                      I-E        9.40     7.77        21%                      I-F       10.22     9.90         3%                                          -40-                                   2004 Compared to 2003                              ---------------------                               Average Sales Prices - --------------------------------------------------------------------------- P/ship                 2004                    2003            % Change - ------          ------------------      ------------------    -------------                   Oil        Gas          Oil        Gas                 ($/Bbl)    ($/Mcf)      ($/Bbl)    ($/Mcf)      Oil    Gas                 -------    -------      -------    -------    -----    ----   I-D            $40.06      $5.38       $28.87      $4.99       39%     8%  I-E             37.56       5.23        27.57       4.89       36%     7%  I-F             37.79       5.48        27.79       5.08       36%     8%                                  Production Volumes - ---------------------------------------------------------------------------  P/ship            2004                    2003                % Change - --------    ------------------      ------------------        -------------              Oil         Gas         Oil           Gas         Oil     Gas             (Bbls)      (Mcf)       (Bbls)        (Mcf)       (Bbls)  (Mcf)             ------     -------      ------       -------      ------  -----    I-D        3,470     147,339       3,764       180,252       ( 8%)   (18%)   I-E       44,611     816,326      53,377       981,953       (16%)   (17%)   I-F       19,943     229,104      23,950       256,653       (17%)   (11%)                             Average Production Costs per                            Barrel of Oil Equivalent                     --------------------------------------                     P/ship     2004      2003     % Change                     ------    -----     -----     --------                       I-D      $6.09     $5.46        12%                      I-E       7.77      6.50        20%                      I-F       9.90      8.12        22%         Liquidity and Capital Resources        Net  proceeds  from  operations  less  necessary   operating  capital  are distributed to the Limited  Partners on a quarterly  basis.  See "Item 5. Market for Units and Related Limited Partner Matters." The net proceeds from production generally are not  reinvested in  productive  assets,  except to the extent that producing  wells are  improved,  where  methods  are  employed  to  permit  more efficient recovery of reserves,  or where identified  developmental  drilling or recompletion opportunities are pursued, thereby resulting in a positive economic impact. Assuming 2005                                          -41-     production levels for future years, the Partnerships'  proved reserve quantities at December 31, 2005 would have the following remaining lives:                    Partnership       Gas-Years      Oil-Years                   -----------       ---------      ---------                        I-D              10.8           20.0                       I-E              10.5           13.4                       I-F              10.4           13.8  These life of reserves estimates are based on the current estimates of remaining oil and gas reserves. See "Item 2. Properties" for a discussion of these reserve estimates.  Any  increase or decrease in the oil and gas prices at December  31, 2005 may cause an increase or decrease in the estimated  life of said  reserves. As discussed below,  the Partnerships  must terminate no later than December 31, 2009, which is four years from December 31, 2005.        The   Partnerships'   available   capital   from  the  Limited   Partners' subscriptions  has been spent on oil and gas properties,  and there should be no further material capital resource commitments for any of the Partnerships in the future. The Partnerships have no debt commitments. Cash for operational purposes will be provided by current oil and gas production. During 2005, 2004, and 2003, the  Partnerships  expended no capital on oil and gas acquisition or exploration activities.  However, during those years the Partnerships expended the following amounts on oil and gas developmental activities, primarily well recompletion and developmental drilling:                 Partnership      2005        2004        2003                -----------    --------    --------    --------                    I-D         $ 25,894    $ 22,991    $ 39,589                   I-E          166,942     116,369     201,567                   I-F           80,581      57,596      92,849  While these expenditures may reduce or eliminate cash available for a particular quarterly cash distribution,  the General Partner believes that these activities are necessary for the prudent  operation of the properties and  maximization  of their value to the Partnerships.        The Partnerships sold certain oil and gas properties during 2004 and 2003. No such sales occurred during 2005. The sale of the Partnerships' properties was made by the General  Partner  after giving due  consideration  to both the offer price and the General  Partner's  estimate of the  property's  remaining  proved reserves and future  operating  costs.  Net  proceeds  from the sale of any such properties  were  included  in  the  calculation  of  the   Partnerships'   cash distributions for the quarter immediately following the Partnerships' receipt of the proceeds. The amount                                          -42-     of such proceeds from the sales of oil and gas properties during 2005, 2004, and 2003, were as follows:               Partnership        2005        2004        2003             -----------       ------      -------     -------                  I-D           $  -        $ 3,715     $   101                 I-E              -         17,915      27,972                 I-F              -          5,546      20,097        Over the years,  as part of the  normal  course of  business,  some of the Partnerships'  interests  in wells  have  been  sold,  generally  at oil and gas auctions.  Given the generally  favorable  current  environment  for oil and gas dispositions,  it is possible that the Partnerships  will increase the number of properties to be sold. In the event of sales,  any net proceeds are  distributed as soon as possible after the disposition.  Future  production,  costs, and cash flow will be reduced as properties are sold.        There can be no  assurance  as to the amount of the  Partnerships'  future cash distributions. The Partnerships' ability to make cash distributions depends primarily upon the level of available  cash flow generated by the  Partnerships' operating  activities,  which will be affected (either positively or negatively) by many factors beyond the control of the  Partnerships,  including the price of and demand for oil and gas and other  market and  economic  conditions.  Even if prices and costs remain stable,  the amount of cash available for  distributions will decline over time (as the volume of production  from  producing  properties declines) since the Partnerships are not generally replacing  production through acquisitions of producing properties and extensive drilling.        The  General  Partner  expects  general  and  administrative  expenses  to increase substantially during 2006 and 2007 due to costs required to comply with Section 404 of the  Sarbanes-Oxley  Act of 2002. Such anticipated  increase will reduce cash available for  distribution.  The General Partner expects at least a portion of this anticipated  increase in general and administrative  expenses to continue in years beyond 2007.        Pursuant  to the terms of the  Partnership  Agreements,  the  Partnerships would have terminated on December 31, 1999. However, the Partnership  Agreements provide that the General Partner may extend the term of each  Partnership for up to five periods of two years each. The General Partner has extended the terms of the Partnerships for the fourth two-year  extension period to December 31, 2007. As of the date of this Annual  Report,  the General  Partner has not  determined whether to further extend the term of any Partnership.                                          -43-           Off-Balance Sheet Arrangements        The Partnerships do not have any off-balance sheet arrangements.         Tabular Disclosure of Contractual Obligations        The  Partnerships  do not have  any  contractual  obligations  of the type required to be disclosed under this heading.         Critical Accounting Policies        The  Partnerships  follow the successful  efforts method of accounting for their  oil  and  gas  properties.  Under  the  successful  efforts  method,  the Partnerships  capitalize all property  acquisition  costs and development  costs incurred in  connection  with the further  development  of oil and gas reserves. Property  acquisition  costs include costs incurred by the  Partnerships  or the General  Partner  to  acquire  producing  properties,  including  related  title insurance or examination costs, commissions,  engineering,  legal and accounting fees, and similar costs directly related to the acquisitions,  plus an allocated portion of the General Partner's  property screening costs. The acquisition cost to the Partnership of properties  acquired by the General Partner is adjusted to reflect  the net cash  results of  operations,  including  interest  incurred to finance the  acquisition,  for the period of time the properties are held by the General Partner.        Depletion of the cost of producing oil and gas properties, amortization of related intangible  drilling and development costs, and depreciation of tangible lease and well  equipment are computed on the  units-of-production  method.  The Partnerships' calculation of depreciation,  depletion, and amortization includes estimated  dismantlement and abandonment costs, net of estimated salvage values. When complete units of depreciable  property are retired or sold, the asset cost and  related  accumulated  depreciation  are  eliminated  with  any gain or loss reflected in income.  When less than complete units of depreciable  property are retired or sold, the proceeds are credited to oil and gas properties.        The  Partnerships  evaluate the  recoverability  of the carrying  costs of their  proved oil and gas  properties  for each oil and gas field  (rather  than separately for each well).  If the  unamortized  costs of oil and gas properties within a field  exceed the  expected  undiscounted  future  cash flows from such properties,  the cost of the properties is written down to fair value,  which is determined by using the discounted  future cash flows from the  properties.  The risk that the Partnerships will be required to record  impairment  provisions in the future increases as oil and gas prices decrease.                                          -44-            The  Deferred  Charge on the  Balance  Sheets  included  in Item 8 of this Annual Report represents costs deferred for lease operating expenses incurred in connection  with  the  Partnerships'   underproduced  gas  imbalance  positions. Conversely, the Accrued Liability represents charges accrued for lease operating expenses  incurred  in  connection  with  the  Partnerships'   overproduced  gas imbalance  positions.  The rate used in  calculating  the  Deferred  Charge  and Accrued Liability is the annual average production costs per Mcf.        The Partnerships' oil and condensate production is sold, title passed, and revenue recognized at or near the Partnerships'  wells under short-term purchase contracts  at  prevailing  prices  in  accordance  with  arrangements  which are customary  in  the  oil  and  gas  industry.  Sales  of  gas  applicable  to the Partnerships'  interest in producing  oil and gas leases are recorded as revenue when  the gas is  metered  and  title  transferred  pursuant  to the  gas  sales contracts covering the Partnerships' interest in gas reserves. During such times as a  Partnership's  sales of gas exceed its pro rata ownership in a well,  such sales are recorded as revenues  unless  total sales from the well have  exceeded the Partnership's share of estimated total gas reserves underlying the property, at which time such excess is recorded as a liability.  The rates per Mcf used to calculate  this  liability  are  based on the  average  gas  price for which the Partnerships are currently settling this liability.  These amounts were recorded as gas  imbalance  payables  in  accordance  with the  sales  method.  These gas imbalance payables will be settled by either gas production by the underproduced party in excess of current  estimates of total gas reserves for the well or by a negotiated or contractual payment to the underproduced party.        The Partnerships' wells must be properly plugged and abandoned after their oil and gas  reserves  are  exhausted.  The  Partnerships  follow  FAS No.  143, "Accounting  for Asset  Retirement  Obligations"  in  accounting  for the future expenditures that will be necessary to plug and abandon these wells. FAS No. 143 requires the estimated plugging and abandonment  obligations to be recognized in the  period  in which  they are  incurred  (i.e.  when  the well is  drilled  or acquired)  if a  reasonable  estimate  of  fair  value  can  be  made  and to be capitalized as part of the carrying amount of the well.         New Accounting Pronouncements        The  Partnerships  are  not  aware  of  any  recently  issued   accounting pronouncements that would have an impact on the Partnerships'  future results of operations and financial position.                                          -45-           Inflation and Changing Prices        Prices obtained for oil and gas production  depend upon numerous  factors, including the extent of domestic and foreign production, foreign imports of oil, market  demand,  domestic  and  foreign  economic  conditions  in  general,  and governmental  regulations  and tax laws.  Inflationary  pressure on drilling and operating  costs have impacted the operating and drilling  costs incurred by the Partnerships.  This  pressure is  expected  to continue to the extent  commodity prices remain at their current levels. Oil and gas prices have fluctuated during recent years and generally have not followed the same pattern as inflation.  See "Item 2. Properties - Oil and Gas Production, Revenue, and Price History."
The Partnerships do not hold any market risk sensitive instruments.
REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM  TO THE PARTNERS  GEODYNE ENERGY INCOME LIMITED PARTNERSHIP I-D GEODYNE PRODUCTION PARTNERSHIP I-D        In our opinion,  the accompanying  combined balance sheets and the related combined  statements of operations,  changes in partners'  capital (deficit) and cash flows present  fairly,  in all material  respects,  the combined  financial position of the  Geodyne  Energy  Income  Limited  Partnership  I-D, an Oklahoma limited partnership, and Geodyne Production Partnership I-D, an Oklahoma general partnership,  at December 31, 2005 and 2004,  and the combined  results of their operations  and their cash flows for each of the three years in the period ended December 31, 2005, in conformity with accounting  principles  generally accepted in  the  United  States  of  America.   These   financial   statements  are  the responsibility of the Partnerships' management. Our responsibility is to express an opinion on these financial  statements based on our audits.  We conducted our audits of these  financial  statements in  accordance  with the standards of the Public Company  Accounting  Oversight  Board (United  States).  Those  standards require that we plan and perform the audit to obtain reasonable  assurance about whether the financial  statements  are free of material  misstatement.  An audit includes  examining,  on a test  basis,  evidence  supporting  the  amounts  and disclosures in the financial  statements,  assessing the  accounting  principles used and  significant  estimates made by management,  and evaluating the overall financial  statement  presentation.   We  believe  that  our  audits  provide  a reasonable basis for the opinion expressed above.        As discussed in Note 1 of Notes to the Combined Financial Statements under the  heading  "Asset  Retirement  Obligation,"  effective  January  1,  2003 the Partnerships  changed  the manner in which  they  account  for asset  retirement obligations.

F-6                 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM  TO THE PARTNERS  GEODYNE ENERGY INCOME LIMITED PARTNERSHIP I-E GEODYNE PRODUCTION PARTNERSHIP I-E        In our opinion,  the accompanying  combined balance sheets and the related combined  statements of operations,  changes in partners'  capital (deficit) and cash flows present  fairly,  in all material  respects,  the combined  financial position of the  Geodyne  Energy  Income  Limited  Partnership  I-E, an Oklahoma limited partnership, and Geodyne Production Partnership I-E, an Oklahoma general partnership,  at December 31, 2005 and 2004,  and the combined  results of their operations  and their cash flows for each of the three years in the period ended December 31, 2005, in conformity with accounting  principles  generally accepted in  the  United  States  of  America.   These   financial   statements  are  the responsibility of the Partnerships' management. Our responsibility is to express an opinion on these financial  statements based on our audits.  We conducted our audits of these  financial  statements in  accordance  with the standards of the Public Company  Accounting  Oversight  Board (United  States).  Those  standards require that we plan and perform the audit to obtain reasonable  assurance about whether the financial  statements  are free of material  misstatement.  An audit includes  examining,  on a test  basis,  evidence  supporting  the  amounts  and disclosures in the financial  statements,  assessing the  accounting  principles used and  significant  estimates made by management,  and evaluating the overall financial  statement  presentation.

These   financial   statements  are  the responsibility of the Partnerships' management. Our responsibility is to express an opinion on these financial  statements based on our audits.  We conducted our audits of these  financial  statements in  accordance  with the standards of the Public Company  Accounting  Oversight  Board (United  States).  Those  standards require that we plan and perform the audit to obtain reasonable  assurance about whether the financial  statements  are free of material  misstatement.  An audit includes  examining,  on a test  basis,  evidence  supporting  the  amounts  and disclosures in the financial  statements,  assessing the  accounting  principles used and  significant  estimates made by management,  and evaluating the overall financial  statement  presentation.   We  believe  that  our  audits  provide  a reasonable basis for the opinion expressed above.        As discussed in Note 1 of Notes to the Combined Financial Statements under the  heading  "Asset  Retirement  Obligation,"  effective  January  1,  2003 the Partnerships  changed  the manner in which  they  account  for asset  retirement obligations.

Limited Partner capital contributions were contributed to the related Production Partnerships   for  investment  in  producing  oil  and  gas   properties.   The Partnerships  were activated on the following  dates with the following  Limited Partner capital contributions:                                                           Limited                                                          Partner                                     Date of              Capital             Partnership           Activation          Contributions             -----------       ------------------      --------------                 I-D            March 4, 1986            $ 7,194,700                I-E            September 10, 1986        41,839,400                I-F            December 16, 1986         14,320,900        The  Partnerships'  original  termination  date  under  their  partnership agreements was December 31, 1999. The General  Partner has extended the terms of the  Partnerships for their fourth two-year period to December 31, 2007 pursuant to its right to extend the term of each  Partnership  for up to five  periods of two years each.        For  purposes  of  these  financial   statements,   the  Partnerships  and Production  Partnerships are collectively  referred to as the "Partnerships" and the general  partner and managing  partner are  collectively  referred to as the "General Partner."        An affiliate of the General  Partner owned the following Units at December 31, 2005:                                          F-19                                     Number of        Percent of             Partnership       Units Owned    Outstanding Units             -----------       -----------    -----------------                I-D               2,199                30.6%                I-E              12,006                28.7%                I-F               4,859                33.9%        The  Partnerships'  sole business is the development and production of oil and gas.  Substantially  all of the  Partnerships'  gas production is being sold regionally  on the "spot  market." Due to the highly  competitive  nature of the spot market, prices on the spot market are subject to wide seasonal and regional pricing  fluctuations.  In  addition,  such  spot  market  sales  are  generally short-term in nature and are dependent  upon obtaining  transportation  services provided  by  pipelines.   The   Partnerships'  oil  is  sold  at  or  near  the Partnerships'   wells  under   short-term   purchase   contracts  at  prevailing arrangements  which are customary in the oil industry.  The prices  received for the  Partnerships'  oil  and gas  are  subject  to  influences  such  as  global consumption and supply trends.         Allocation of Costs and Revenues        The Partnerships have achieved payout and therefore the combination of the allocation  provisions in each Partnership's  limited partnership  agreement and each  Production   Partnership's   partnership  agreement   (collectively,   the "Partnership  Agreement") results in allocations of costs and income between the Limited Partners and General Partner as follows:                                           F-20                                                 General     Limited                                             Partner     Partners             Costs(1)                        --------    --------      ------------------------      Property acquisition          costs                                 1%         99%      Identified development          drilling                              1%         99%      Development drilling                     15%         85%      General and administra-      tive costs, direct          administrative costs          and operating costs                  15%         85%            Income(1)      ------------------------      Temporary investments of      Limited Partners'          capital contributions                 1%         99%      Income from oil and gas          production                           15%         85%      Sale of producing pro-          perties                              15%         85%      All other income                         15%         85%  - ---------- (1)   The allocations in the table result  generally from the combined effect of       the allocation provisions in the Partnership Agreements.  For example, the       costs  incurred in  development  drilling  are  allocated  85.8586% to the       limited  partnership  and 14.1414% to the managing  partner.  The 85.8586%       portion of these costs allocated to the limited  partnership,  when passed       through the limited  partnership,  is further allocated 99% to the limited       partners  and 1% to the  general  partner.  In  this  manner  the  Limited       Partners  are  allocated  85% of such  costs and the  General  Partner  is       allocated 15% of such costs.         Basis of Presentation        These  financial   statements   reflect  the  combined  accounts  of  each Partnership  after the  elimination of all  inter-partnership  transactions  and balances.         Cash and Cash Equivalents        The Partnerships consider all highly liquid investments with a maturity of three months or less when purchased to be cash equivalents. Cash equivalents are not insured, which cause the Partnerships to be subject to risk.                                           F-21           Credit Risk        Accrued  oil and gas sales  which  are due from a  variety  of oil and gas purchasers  subject the  Partnerships to a concentration of credit risk. Some of these purchasers are discussed in Note 3 - Major Customers.         Oil and Gas Properties        The  Partnerships  follow the successful  efforts method of accounting for their  oil  and  gas  properties.  Under  the  successful  efforts  method,  the Partnerships  capitalize all property  acquisition  costs and development  costs incurred in  connection  with the further  development  of oil and gas reserves. Property  acquisition  costs include costs incurred by the  Partnerships  or the General  Partner  to  acquire  producing  properties,  including  related  title insurance or examination costs, commissions,  engineering,  legal and accounting fees, and similar costs directly related to the acquisitions,  plus an allocated portion of the General Partner's  property screening costs. The acquisition cost to the Partnerships of properties acquired by the General Partner is adjusted to reflect  the net cash  results of  operations,  including  interest  incurred to finance the  acquisition,  for the period of time the properties are held by the General Partner.        Depletion of the cost of producing oil and gas properties, amortization of related intangible  drilling and development costs, and depreciation of tangible lease and well  equipment are computed on the  units-of-production  method.  The Partnerships' depletion,  depreciation,  and amortization includes dismantlement and  abandonment  costs,  net of  estimated  salvage  value.  The  depreciation, depletion,  and  amortization  rates,  which  include  accretion  of  the  asset retirement  obligation,  per equivalent  barrel of oil produced during the years ended December 31, 2005, 2004, and 2003, were as follows:              Partnership        2005        2004        2003             -----------       -----       -----       -----                  I-D           $1.51       $1.19       $2.15                 I-E            2.17        1.08        2.24                 I-F            3.20        1.18        1.22        When complete units of depreciable property are retired or sold, the asset cost,  related   accumulated   depreciation,   and  remaining  asset  retirement obligation,  are eliminated with any gain or loss reflected in income. When less than complete  units of  depreciable  property are retired or sold, the proceeds are credited to oil and gas properties.        The  Partnerships  evaluate the  recoverability  of the carrying  costs of their proved oil and gas properties at the field level.                                          F-22     If the  unamortized  costs of oil and gas  properties  within a field exceed the expected  undiscounted  future cash flows from such properties,  the cost of the properties  is written  down to fair  value,  which is  determined  by using the discounted future cash flows from the properties.  No impairment provisions were recorded by the Partnerships during the three years ended December 31, 2005. The risk that the Partnerships will be required to record  impairment  provisions in the future increases as oil and gas prices decrease.         Deferred Charge        The Deferred Charge represents costs deferred for lease operating expenses incurred  in  connection  with the  Partnerships'  underproduced  gas  imbalance positions.  The rate used in  calculating  the  deferred  charge is the  average annual production costs per Mcf. At December 31, 2005 and 2004, cumulative total gas sales  volumes  for  underproduced  wells  were less than the  Partnerships' pro-rata  share  of total  gas  production  from  these  wells by the  following amounts:                                    2005                      2004                          ---------------------     ----------------------       Partnership          Mcf         Amount        Mcf          Amount       -----------        -------      --------     -------       --------            I-D            146,979      $ 77,179     157,314       $ 82,606           I-E            591,655       394,160     636,910        424,309           I-F            246,365       302,265     266,208        326,610         Accrued Liability - Other        The Accrued  Liability  - Other at  December  31, 2004 for the I-E and I-F Partnerships  represents a charge accrued for the payment of a judgment  related to plugging liabilities. The decrease in Accrued Liability - Other from December 31,  2004 to December  31,  2005 was due to a ruling  made by the Texas  Supreme Court on April 8, 2005 that the Partnerships did not owe this liability.         Accrued Liability        The Accrued  Liability  represents  charges  accrued  for lease  operating expenses  incurred  in  connection  with  the  Partnerships'   overproduced  gas imbalance  positions.  The rate used in calculating the accrued liability is the average  annual  production  costs  per Mcf.  At  December  31,  2005 and  2004, cumulative  total  gas  sales  volumes  for  overproduced   wells  exceeded  the Partnerships'  pro-rata  share of total gas  production  from these wells by the following amounts:                                          F-23                                          2005                      2004                         ----------------------     --------------------       Partnership         Mcf          Amount        Mcf        Amount       -----------       -------       --------     -------     --------            I-D            47,728       $ 25,062      57,956     $ 30,433           I-E           184,473        122,896     236,623      157,638           I-F            93,100        114,225     113,386      139,114         Oil and Gas Sales and Gas Imbalance Payable        The Partnerships' oil and condensate production is sold, title passed, and revenue recognized at or near the Partnerships'  wells under short-term purchase contracts  at  prevailing  prices  in  accordance  with  arrangements  which are customary in the oil  industry.  Sales of gas  applicable  to the  Partnerships' interest in producing oil and gas leases are recorded as revenue when the gas is metered and title transferred  pursuant to the gas sales contracts  covering the Partnerships'  interest in gas  reserves.  During such times as a  Partnership's sales of gas exceed its pro rata ownership in a well, such sales are recorded as revenue unless total sales from the well have exceeded the  Partnership's  share of estimated  total gas reserves  underlying  the  property,  at which time such excess is  recorded as a  liability.  The rates per Mcf used to  calculate  this liability  are based on the  average gas prices for which the  Partnerships  are currently  settling this liability.  At December 31, 2005 and 2004,  total sales exceeded the Partnerships' share of estimated total gas reserves as follows:                                   2005                       2004                          -------------------        ------------------       Partnership         Mcf        Amount          Mcf       Amount       -----------        ------     --------        ------    --------            I-D            21,978     $ 32,967        23,058    $ 34,587           I-E            74,682      112,023        78,175     117,263           I-F            24,115       36,173        25,240      37,860  These  amounts were recorded as gas  imbalance  payables in accordance  with the sales  method.  These gas  imbalance  payables  will be  settled  by either  gas production by the  underproduced  party in excess of current  estimates of total gas  reserves  for the well or by a  negotiated  or  contractual  payment to the underproduced party.                                          F-24           The Partnerships have not entered into any hedging or derivative contracts in connection with their production and sale of oil and gas.         General and Administrative Overhead        The General  Partner and its  affiliates are reimbursed for actual general and  administrative  costs  incurred  and  attributable  to the  conduct  of the business affairs and operations of the Partnerships.         Use of Estimates in Financial Statements        The  preparation  of financial  statements  in conformity  with  generally accepted  accounting  principles  requires  management  to  make  estimates  and assumptions  that  affect the  reported  amounts of assets and  liabilities  and disclosure of  contingent  assets and  liabilities  at the date of the financial statements  and the  reported  amounts  of  revenues  and  expenses  during  the reporting period. Actual results could differ from those estimates. Further, the deferred charge,  the gas imbalance payable,  the asset retirement  obligations, and the accrued  liability all involve  estimates which could materially  differ from the actual  amounts  ultimately  realized or incurred in the near term. Oil and gas reserves  (see Note 4) also involve  significant  estimates  which could materially differ from the actual amounts ultimately realized.         Asset Retirement Obligation        The Partnerships' wells must be properly plugged and abandoned after their oil and gas reserves are exhausted.  FAS No. 143 requires the estimated plugging and  abandonment  obligations  to be  recognized in the period in which they are incurred (i.e. when the well is drilled or acquired) if a reasonable estimate of fair value can be made and to be capitalized  as part of the carrying  amount of the well.  Estimated  abandonment  dates will be revised in the future  based on changes to related economic lives, which vary with product prices and production costs.  Estimated  plugging  costs  may also be  adjusted  to  reflect  changing industry  experience.  On January 1, 2003, the Partnerships  adopted FAS No. 143 "Accounting  for Asset  Retirement  Obligations"  and  recorded  an  increase in capitalized cost of oil and gas properties, an increase (decrease) in net income for the cumulative  effect of the change in accounting  principle,  and an asset retirement   obligation.   During  the  year  ended   December  31,  2005,   the Partnerships'  asset  retirement  obligations  were  revised  upward  due  to an increase in both the labor and rig costs  associated with plugging  wells.  Cash flows would not be affected until wells are actually plugged and abandoned.                                          F-25             The asset retirement  obligation is adjusted upwards each quarter in order to recognize  accretion of the time-related  discount factor. For the year ended December 31, 2005, the I-D, I-E, and I-F Partnerships  recognized  approximately $13,000, $214,000, and $125,000,  respectively,  of an increase in depreciation, depletion,  and  amortization  expense,  which was comprised of accretion of the asset retirement obligation and depletion of the increase in capitalized cost of oil and gas properties.        The components of the change in asset retirement obligations for the years ended December 31, 2005 and 2004 are as shown below.

TRANSACTIONS WITH RELATED PARTIES        The  Partnerships  reimburse  the  General  Partner  for the  general  and administrative  overhead applicable to the Partnerships,  based on an allocation of actual costs  incurred by the General  Partner.  When actual  costs  incurred benefit other  Partnerships and affiliates,  the allocation of costs is based on the  relationship of the  Partnerships'  reserves to the total reserves owned by all  Partnerships  and affiliates.  The General Partner believes this allocation method is reasonable.  Although the actual costs incurred by the General Partner and its affiliates have fluctuated during the three years presented, the amounts charged  to the  Partnerships  have not  fluctuated  every  year due to  expense limitations imposed by the Partnership Agreements. The following is a summary of payments made to the General Partner or its affiliates by the  Partnerships  for general and administrative overhead costs for the years ended December 31, 2005, 2004, and 2003:              Partnership         2005         2004         2003             -----------       --------     --------     --------                  I-D           $ 79,944     $ 79,944     $ 79,944                 I-E            464,880      464,880      464,880                 I-F            159,120      159,120      159,120        Affiliates  of the  Partnerships  operate  certain  of  the  Partnerships' properties  and  their  policy  is to bill the  Partnerships  for all  customary charges and cost reimbursements associated with these activities,  together with any compressor rentals, consulting, or other services provided.

Audit Committee Financial Expert        The  Partnerships  are not  required by SEC  regulations  or  otherwise to maintain an audit  committee.

Such request must include the address to which the Code of Ethics should be mailed.
The General  Partner and its  affiliates are reimbursed for actual general and  administrative  costs and operating costs incurred and  attributable to the conduct of the business affairs and operations of the Partnerships,  computed on a cost basis,  determined  in  accordance  with  generally  accepted  accounting principles.  Such reimbursed  costs and expenses  allocated to the  Partnerships include office rent, secretarial, employee compensation and benefits, travel and communication costs, fees for professional  services,  and other items generally classified  as general or  administrative  expense.  When actual costs  incurred benefit other  Partnerships and affiliates,  the allocation of costs is based on the  relationship of the  Partnerships'  reserves to the total reserves owned by all  Partnerships  and  affiliates.  The  amount of general  and  administrative expense allocated to the General Partner and its affiliates which was charged to each  Partnership  for 2005,  2004,  and 2003,  is set forth in the table below. Although the actual  costs  incurred by the General  Partner and its  affiliates have fluctuated during the three years                                          -48-     presented, the amount charged to the Partnerships have not fluctuated every year due to expense limitations imposed by the Partnership Agreements.

The General  Partner  contracts with such  affiliates for services as operator of the wells. As operator,  such affiliates are compensated at rates  provided  in the  operating  agreements  in effect and  charged to all parties to such agreement. Such compensation may occur both prior and subsequent to the  commencement  of  commercial  marketing of production of oil or gas. The dollar amount of such compensation paid by the Partnerships to the affiliates is impossible to quantify as of the date of this Annual Report.        Samson  maintains  necessary  inventories of new and used field equipment. Samson  may  have  provided  some of this  equipment  for  wells  in  which  the Partnerships  have an interest.  This  equipment was provided at prices or rates equal  to or  less  than  those  normally  charged  in the  same  or  comparable geographic  area by unaffiliated  persons or companies  dealing at arm's length. The operators of these wells billed the Partnerships for a portion of such costs based upon the Partnerships' interest in the well.

The General  Partner and certain of its  affiliates  engage in oil and gas activities  independently  of the  Partnerships  which  result in  conflicts  of interest that cannot be totally  eliminated.  The allocation of acquisition  and drilling  opportunities and the nature of the compensation  arrangements between the  Partnerships  and the General  Partner also create  potential  conflicts of interest.  An affiliate of the Partnerships owns some of the Partnerships' Units and  therefore  has an identity of interest  with other  Limited  Partners  with respect to the operations of the Partnerships.        In order to attempt to assure  limited  liability for Limited  Partners as well as an orderly  conduct  of  business,  management  of the  Partnerships  is exercised  solely by the General Partner.  The Partnership  Agreements grant the General Partner broad discretionary  authority with respect to the Partnerships' participation  in  drilling  prospects  and  expenditure  and  control of funds, including  borrowings.  These  provisions  are  similar  to those  contained  in prospectuses   and   partnership   agreements  for  other  public  oil  and  gas partnerships.  Broad  discretion as to general  management  of the  Partnerships involves  circumstances  where the General Partner has conflicts of interest and where  it  must  allocate  costs  and  expenses,  or  opportunities,  among  the Partnerships and other competing interests.        The  General  Partner  does  not  devote  all of its  time,  efforts,  and personnel exclusively to the Partnerships.  Furthermore, the Partnerships do not have  any  employees,   but  instead  rely  on  the  personnel  of  Samson.  The Partnerships thus compete with Samson (including other oil and gas partnerships)                                          -54-     for the time and  resources  of such  personnel.  Samson  devotes  such time and personnel  to  the  management  of the  Partnerships  as  are  indicated  by the circumstances and as are consistent with the General Partner's fiduciary duties.        Affiliates of the Partnerships are solely responsible for the negotiation, administration,  and  enforcement of oil and gas sales  agreements  covering the Partnerships'  leasehold  interests.  Because affiliates of the Partnerships who provide  services to the  Partnerships  have  fiduciary or other duties to other members of Samson,  contract amendments and negotiating  positions taken by them in their  effort  to  enforce  contracts  with  purchasers  may not  necessarily represent  the  positions  that  the  Partnerships  would  take if they  were to administer their own contracts without involvement with other members of Samson. On the  other  hand,  management  believes  that the  Partnerships'  negotiating strength  and  contractual  positions  have  been  enhanced  by  virtue of their affiliation with Samson.
Audit Fees        During 2005 and 2004, each Partnership paid the following audit fees:                                                   2005        2004                                                 -------     -------        Year-end audit per engagement letter      $23,716     $21,560       1st quarter 10-Q review                       925         825       2nd quarter 10-Q review                       917         825       3rd quarter 10-Q review                       917         825         Audit-Related Fees        During 2005 and 2004 the Partnerships did not pay any  audit-related  fees of the type required by the SEC to be disclosed in this Annual Report under this heading.         Tax Fees        During 2005 and 2004 the Partnerships did not pay any tax compliance,  tax advice,  or tax planning fees of the type required by the SEC to be disclosed in this Annual Report under this heading.                                          -55-           All Other Fees        During  2005 and 2004 the  Partnerships  did not pay any other fees of the type  required  by the SEC to be  disclosed  in this  Annual  Report  under this heading.         Audit Approval        The  Partnerships  do not have audit committee  pre-approval  policies and procedures as described in paragraph  (c)(7)(i) of Rule 2-01 of Regulation  S-X. The  Partnerships  did not receive any  services of the type  described in Items 9(e)(2) through 9(e)(4) of Schedule 14A.         Audit and Related Fees Paid by Affiliates        The  Partnerships'  accountants  received  compensation from other related partnerships  managed by the General Partner and from other entities  affiliated with the General Partner.  This compensation is for audit services,  tax related services,  and other  accounting-related  services. The General Partner does not believe this arrangement creates a conflict of interest or impairs the auditors' independence.                                        PART IV.
