PTTEP reported in late July 2018 that it is seeking potential partners in Block M-11, located between the Moattama Basin and the Andaman Sea Basin. The company intends to share the exploration risk in the block, which is located immediately south of the Zawtika Development and production area. Block M-11 is located primarily in deep water, with a maximum depth of approximately 2,000 m.  PTTEP is preparing for an exploration drilling campaign that will include one or two wells in Block M-11, where no discoveries have been made to date. The campaign will also include up to twelve appraisal wells in Block M-09, with the goal of identifying further reserves upside for the Zawtika gas project. PTTEP has contracted the âNoble Clyde Boudreauxâ S/S for the campaign, which is expected to commence in Q3 2018.  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 also drilled one well in the block, Manizawta 1, in 2013. The primary target, Miocene carbonates, was dry, however possible gas shows were encountered in the shallower Pliocene sandstone section.  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.  The potential geological targets in this area are Oligocene-Miocene carbonate rocks, basin floor fan deposits and shallow marine to deltaic sandstone beds within the Middle and Upper Miocene intervals.  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.
