Pan Orient is planning to drill two appraisal wells within the L53 DD field in L53 DD Production Area (PA), onshore Chao Phraya Basin, in August 2019. L53 DD5 and L53 DD6 wells will be drilled from the same well pad as the previous four wells within the L53 DD field.  The wells could be targeting to access the extension of BB/CC sand, the main producer in the field. The estimated cost for both wells would be around USD 900,000 for dry hole cases.     The last appraisal well, L53 DD3 was drilled in March 2019. In mid-May 2019, the well was tested at an average of 1,854 b/d of oil from the commingled DD/EE, BB/CC and BB sands.Â      Since December 2018, three appraisal wells have been drilled within the L53 DD PA, immediately after the discovery in L53 DD1. The appraisal wells have contributed to an additional 150% for 2P and 65% for 1P, which has accelerated the approval of Production License in late April 2019. The production in the L53 DD PA has increased 600% since the discovery of L53 DD in December 2018.    As of April 2019, the concession holds remaining crude oil reserves of 2.7 MMbbl from the Lower Miocene sandstone reservoir.    The L53/48 concession is fully owned and operated by Pan Orient (Siam) Ltd, which is in turn controlled by Pan Orient Energy Corp (50.01%) and Sea Oil Public Company (49.99%). The exploration Area A and B will expire in January 2021, after which the production areas (A, B, D, G and DD) will be retained.    Background Information   The L53/48 block lies onshore in the Kamphaeng Saen Sub-basin of the Chao Phraya Basin, around 50km WNW of Bangkok. The area is covered by at least 580 sq km of 3D seismic data which were acquired since 2007.     Seven minor oil discoveries were encountered within the L53/48 concession from 2009 to 2018. To date, a total of four fields are producing (L53-A, L53-G, L53-D East and L53-DD), one is developing (L53-B) and another two fields are appraising (L53-D and L53-D C-EXT). The oils were structurally trapped in the Lower to Middle Miocene Sandstone Series which was sealed by Middle Miocene Series mudstone.     The original 3,997 sq km L53/48 block was awarded to Pan Orient Energy on 8 January 2007 as the operator and sole interest holder, under the 19th Licensing Round. The concession agreement allows Pan Orient to explore for hydrocarbons over a period of six years with a minimum three years first phase commitment of approximately US$ 2.1 million, which includes 3D seismic acquisition and two exploratory wells.    In late 2016 and 2017, the operator attempted to find several upside potentials within the Miocene sandstone reservoirs by drilling L53-ANE-A1 and L53 AC C1 in the Reserve Area A. The wells failed to encounter hydrocarbons within the target intervals, which were determined to have excellent quality of sandstones.     In November 2018, the L53 DD field was discovered by L53 DD1 wildcat. Oils were trapped in the Lower to Middle Miocene Sandstone Series structural play sealed by Middle Miocene Series mudstone. The daily oil production for L53 DD1 is around 530 barrels, based on the reported cumulative production from 21 November 2018 to 10 February 2019. This discovery was immediately appraised by L53 DD2 well. Both wells have been shut-in after the completion of production test in February 2019, until an approval is granted for L53 DD field Production License by the Department of Energy Fuel (DMF). The approval is anticipated to be granted in April/May 2019.
