In April 2018, PEMEX commenced an extended well test (EWT) of the Ixachi 1 gas and condensate discovery.Â  Through August 2018, the well has tested an average of 8.18 MMcfg/d and 1,146 bc/d. Â The operator is conducting testing operations through the A-0269-M-Campo Perdiz production facitilities.Â  The highest average production rate occurred in May 2018 at 10.03 MMcfg/d and 1,442 bc/d.Â  The latest month average production in August 2018 was 7.1 MMcfg/d and 1,026 bc/d.Â  The EWT is part of the CNH approved evaluation plan.Â  PEMEX continues operating on the first outpost well the Ixachi 1DEL directional outpost during late-September 2018.Â      On 15 March 2018, the CNH granted approval for the discovery evaluation plan submitted by operator PEMEX for the Ixachi 1 new-field wildcat (NFW) gas and condensate discovery in the AE-0032-2M-Joachin-02 entitlement block in the onshore Veracruz Basin on 5 November 2017.Â  The evaluation plan also includes the southerly adjoining AE-0028-2M-Cotaxtla-01 entitlement.Â  The evaluation plan includes the firm commitments of drilling one outpost well the Ixachi 1DEL, and an extended well test (EWT).Â Â  The drilling of the outpost and the EWT will commence by April 2018.Â  The EWT will conclude in September 2018.Â  A contingent commitment is the drilling of the Ixachi 2DEL outpost well that would spud in August or September 2018.Â  Additional information was reported regarding the reservoir properties and the production tests conducted on the discovery well.Â  The Ixachi mapped structure covers an approximate area of 56 sq km.Â  The Ixachi 1DEL will be located approximately 4.4 km south-east of the Ixachi 1 discovery well.Â  The Ixachi 2DEL will be located approximately 5.2 km south-east of the Ixachi 1DEL outpost well.Â  PEMEX tested two intervals in the discovery well, the first from 6,560 m to 6,620 m and the second zone from 6,854 m to 6,904 m.Â  Both zones were stimulated with acid fracture treatments which resulted in three-fold productivity gains from the production tests with only perforations.Â  The highest production was reported for the upper zone and this was 29.93 MMcfg/d and 3,269.30 bc/d 40.3Â° API after acid-frac through a 32/64â choke. The Ixachi 1 is a high temperature, high pressure reservoir with reservoir temperature reported to be 161Â° C and bottom hole pressure (BHP) is 17,102 psi with a shut-in tubing pressure (SITP) of 12,780 psi.Â  There is 1.35% CO2 and 0.033% H2S in the reservoir fluids.Â  No details regarding porosity and perm was reported but they were reported to be variable, due to the various reefal facies encountered in the reservoir section.      On 26 February 2018, PEMEX reported with its 4th quarter 2017 results that the well tested 28.9 MMcfg/d and 3,269 bc/d.Â  It also reported that it will incorporate 3P reserves in 2017 of 366.3 MMboe attributed to the discovery.Â Â  Â      In early-February 2018, the CNH published some information on the NFW.Â  The CNH reported the well reached a final total depth (TD) of 7,700 m and that the productive zone is at 6,854 m to 6,904 m, in the objective Lower Cretaceous Orizaba Formation.Â Â  Â      On 3 November 2017, PEMEX issued a press release indicating the well has estimated in place resources of 1.5 Bboe with recoverable reserves estimated to be potentially in the 350 MMboe range.Â Â  Â      The NFW was spudded on 25 January 2017 after receiving approval from the CNH on 20 September 2016.Â Â  Â      The well had a proposed total depth (PTD) of 7,728 m.      The Middle and Lower Cretaceous Formation, Orizaba Formation, were the main objectives.Â Â  Â      The well represents a significant Cretaceous test that represents the deepest well ever drilled in the Veracruz Basin and is a new play-opener in this area of the Veracruz Basin.    The Ixachi prospect is a four way closure on a northwest to southeast trending anticlinal feature above a prominent basement high and underlying a thrust fault. The Middle Cretaceous Formation is the main objective from 6,368 m to 7,048 m and the Lower Cretaceous Formation is a secondary objective from 7,228 m to 7,498 m.Â  The Middle and Lower Cretaceous formations consist of a basin-ward prograding reef and associated talus facies. It is speculated to be a basin-ward continuation of the Cordoba Platform carbonate trend 20 km to the west and similar to the Golden Lane El Abra reef trend located 200 km to the north.Â  The nearest deep Cretaceous test drilled was the Torcaza 101A located 29 km to the northwest.Â  The well was plugged and abandoned with results unreported, assumed dry hole, in 1981 and a total depth (TD) of 6,741 m.Â  The Mecayucan 1 discovery and field is the principal analogue located 8 km northwest of the Torcaza 101A.Â  The well is located higher on the platform but was productive from the Lower Cretaceous.Â  The Ixachi 1 is a high temperature, high pressure well with target formation temperatures estimated to be 167Â° C and bottom hole pressure (BHP) estimated at 11,305 psi with a wellhead pressure (WHP) estimated at 4,550 psi.  SENER awarded the AE-0032-2M-Joachin-02 block entitlement to Pemex 100% through Ronda 0 on 27 August 2014. The operator was granted a two year extension for the entitlement on 27 August 2017.Â  The block covers an approximate area of 976.40 sq km.
