PTTEP is believed to have plugged and abandoned wildcat Pundarika 1 located in the western part of block M-09, Moattama Basin, in early November 2019, with results unreported.  The well, spudded around late September 2019, was drilled using the "Noble Clyde Boudreaux" S/S. Possible drilling targets may include Pliocene sandstones of the Moattama Series and Oligo-Miocene carbonates of the Burman Limestone.  Pundarika 1 is the first of three exploration wells planned to be drilled in the "M9 west" area between late 2019 and early 2020. The planned TD for the wells could be approximately 3,000-3,500 m TVDSS. The other wells in the programme are Aungpyitan 1 and Uppala 1.  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. The well was plugged and abandoned in June 2019 as dry.  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.  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.
