PTTEP is understood to have abandoned wildcat Aungpyitan 1 in the western part of block M-09, Moattama Basin, as a dry well, around mid-January 2020. The well was drilled to a TD estimated at approximately 3,500 m, with bottom hole in volcanics.  Operations were conducted using the "Noble Clyde Boudreaux" S/S, at a water depth of around 100 m.  As of early January 2020, the well had reached a depth of approximately 3,250 m prior to being drilled ahead towards TD section. Previously, the well was being drilled at approximately 1,750 m in early December 2019.  Aungpyitan 1 was spudded in late November 2019 and had a PTD of approximately 3,720 m. Possible drilling targets included Pliocene sandstones of the Moattama Series and Oligo-Miocene carbonates of the Burman Limestone.  Aungpyitan 1 was the second of three exploration wells originally planned to be drilled in the "M9 West" area between late 2019 and early 2020. The first well, Pundarika 1ST, was spudded in late August 2019 and P&A in mid-November 2019, likely as a dry well. Pundarika 1ST is located about 45 km east of Aungpyitan 1. The third proposed drilling location, Uppala 1, is approximately 15 km northeast of Aungpyitan 1.  Operations are expected to take up to approximately 40 days for each well, including rig mobilization, drilling and well abandonment.  The "Noble Clyde Boudreaux" has been operating for PTTEP since late 2018 to conduct an appraisal drilling campaign in the central and eastern part of block M-09 (Zawtika field area) and exploration drilling in block M-11. The latter activity consisted of wildcat Pyae Wa Chan Thar 1, which was plugged and abandoned in June 2019 as dry. The rig is under contract with PTTEP until May 2020.  PTTEP is operator of block M-09 with 80% interest, while MOGE holds the remaining 20%. The adjacent exploration block M-11 to the south is operated by PTTEP with 100% interest, however the company applied to relinquish the block in Q3 2019, following the unsuccessful drilling results.  Background Information  The last exploration well in the western part of block M-09 was Bawga Siddhi 1. The well was plugged and abandoned in September 2010. The well experienced abnormal over pressured zone and gas influx in the wellbore which caused the operator to terminate drilling at 3,052 m, shallower than the PTD of 4,089 m, due to safety reasons. The well failed to reach its drilling objectives but the operator confirmed the presence of net pay, 19 m of gas bearing sandstone above the not-reached objectives.  PTTEP reported that the Zawtika Project commenced gas production for the domestic market on 14 March 2014, with initial sales rate of 40 MMscfg/d and planned peak of 100 MMcfg/d. Domestic gas is used for power generation.  Gas export to Thailand commenced on 5 August 2014. Production gradually ramped up to the daily contract quantity of 240 MMscfg/d as stipulated in the Gas Sales Agreement with buyer PTT.  Due to the highly faulted structures, numerous platforms and wells are required to develop the Zawtika and nearby fields. The initial phase of the Zawtika project (Phase 1A) consisted of three wellhead platforms (ZWP1, ZWP2 and ZWP3, located in the Shwepyihtay, Kakonna and Zawtika fields respectively) and one integrated central processing/living quarterâs platform (ZPQ). Further development phases will be necessary in order to maintain the stipulated production plateau.
Aungpyitan 1 (PTTEP 80% op, MOGE 20%), W. part of M-09 block, understood P&A dry. Targets possibly Moattama Series sst + Burman limestone. WD=103m, TD perhaps around 3500m (volcanics), P&A dry.
