PTTEP has plugged and abandoned wildcat Pyae Wa Chan Thar 1 in Block M-11, straddling the Moattama Basin and the Andaman Sea Basin, around late June 2019. Initial results have not been reported, however it is understood that a series of MDT tests indicated tight reservoir.   The well was drilled to a final TD of approximately 4,030 m MD using the âNoble Clyde Boudreauxâ S/S, at a water depth of approximately 600 m. The potential geological targets in this area include Oligocene-Miocene carbonate rocks, shallow marine to deltaic sandstone beds within the Middle and Upper Miocene intervals and Pliocene basin floor fan deposits.    As of May 2019, operations were ongoing around 3,800 m. Wireline logging and coring was conducted during drilling.  Pyae Wa Chan Thar 1 was spudded in early April 2019. Late in the month, drilling was likely ongoing at approximately 2,000 m.     There are no discoveries made to date in block M-11. The only well previously drilled in the block is wildcat Manizawta 1 by PTTEP, in 2013. The primary target, Miocene carbonates, was dry, however possible gas shows were encountered in the shallower Pliocene sandstone section. Pyae Wa Chan Thar 1 is located approximately 25 km northeast of Manizawta 1.    PTTEP has contracted the âNoble Clyde Boudreauxâ for an extended drilling campaign since Q3 2018, to conduct appraisal drilling over the Zawtika gas complex, in the eastern part of block M-09, and new-field wildcat drilling in block M-11 and in the western part of block M-09.    The previous exploration activity in Block M-11 was a 3D seismic survey acquired in 2016 using the âPolarcus Asimaâ vessel. The planned area for the survey was approximately 1,500 sq km.     PTTEP holds 100% operating interest in Block M-11. The company also operates the Zawtika Development and Production Area (80% interest), partnering with MOGE (20%).    Background Information    Block M-11 was awarded to PTTEP (100%) in 2005. In 2012, Total and JX Nippon farmed into the block for 40% and 15% interests respectively. Following the drilling of wildcat Manizawta 1 in 2013, the partners withdrew from the block, leaving PTTEP as sole interest holder.    PTTEP plugged and abandoned new-field wildcat Manizawta 1 on 4 November 2013. The well was drilled to TD at around 3,550 m. The well was spudded on 21 September 2013 by Vantage Drillingâs drillship âTungsten Explorerâ. The prospect is located in the deeper section of the block at around 1,000 m of water depth. Manizawta 1 is approximately 47 km west of wildcat M-11A/1 drilled by Esso Burma in 1976.    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.
