Woodside has plugged and abandoned wildcat Dhana Hlaing 1 in Block A-7, located in the southern part of the Rakhine Basin, on 18 July 2018. Well results have not been reported, as further assessment is underway. The well was drilled to a TD of 4,500 m, slightly shallower than the PTD of 4,526 m.  Dhana Hlaing 1 was spudded on 26 June 2018 using Transoceanâs âDhirubhai Deepwater KG2â D/S. As of early July 2018, operations were ongoing at a drilled depth around 2,800 m.  Dhana Hlaing 1 is located in the western part of Block A-7, at a water depth of 2,057 m. The well likely targeted a dry gas prospect within Pliocene turbidite sandstones. Analogy with previous discoveries made in the adjacent Block A-6 to the north (Shwe Yee Htun 1, Pyi Thit 1) suggests large prospective resources, estimated by the operator to exceed 100 MMboe.  The âDhirubhai Deepwater KG2â was hired by Woodside in November 2017. The firm five-month contract will run from May to October 2018. Dhana Hlaing 1 is the second well in the campaign, following the Aung Siddhi 1 gas discovery in block AD-1, located in the northern part of the basin.  A preliminary cost estimation for the drilling campaign in Block A-7, as of December 2017, was at approximately USD 60 million.    Water depths in the area range from around 200 m in the eastern part of the block, to more than 2,000 m in the west. The turbidite plays targeted in the southern Rakhine Basin are interpreted to derive from the paleo-Irrawaddy fluvial system, unlike the northern part of the basin (Shwe complex, Thalin) where the terrigenous influx is derived from the Ganges-Brahmaputra fluvial system.  The western area of Block A-7 is covered by 2D and 3D seismic data acquired between late 2015 and early 2016. In May 2017, Woodside reported a plan for an additional 3D seismic acquisition in the eastern sector of the block.    Woodside is the operator of Block A-7 with 45% interest. The other participants are Shell (formerly BG Group) with 45% interest and MPEP (a subsidiary of local company MPRL) with 10%.    Background Information    Myanmar Oil and Gas Enterprise (MOGE) signed Production Sharing Contracts (PSCs) for blocks A-4, A-7, AD-2 and AD-5 with Woodside Australia, BG Group and MPRL Pte Ltd on 20 March 2015. A new acquisition of 3D seismic data is included as a work commitment for each block. Values of total commitment work for four blocks are estimated at USD 1.1 billion. The signing of the PSCs was the result of the 2013 Myanmar Offshore Bid Round.  From November 2015 to April 2016, Woodside acquired 3D seismic data over the western part of block A-7 and adjacent blocks AD-5 and A-6. The survey (âThazin 3Dâ) was conducted using PGSâs âRamform Titanâ survey vessel. A total of approximately 14,000 sq km of 3D seismic data were acquired. An additional 2D seismic survey (âSabae 2Dâ) was conducted over block A-7 in April 2016, consisting of 1,295 km of 2D seismic data.    In December 2016, Woodside conducted a seabed survey over blocks A-7 and AD-5, comprising multi-beam echosounder survey and sea floor coring.    One exploratory well, A-7 1, has been drilled in the shallow water portion of Block A-7. The well, drilled in 1976 by Cities Service Co, was plugged and abandoned as dry, without testing.
Dhana Hlaing 1 in Block A-7, P&A, results have not been reported, as further assessment is underway. Dry well most probably.
