Thalin-1A exploration well in Block AD-7 in the Rakhine Basin has intersected a gross gas column of approximately 64m, Woodside informed.
Block AD-7 is located in the Bay of Bengal, approximately 100km offshore of the west coast of Myanmar. Water depth at the Thalin-1A well location is 836m.
The well reached a total depth of 3034m, referenced from the rig rotary table. Following drilling, wireline logging was conducted and confirmed the presence of a gas column through pressure measurements and gas sampling.
The gas discovery at Thalin-1A follows an earlier gas discovery by Woodside at the Shwe Yee Htun-1 well in Block A-6, announced on January 04, 2016.
Woodside CEO Peter Coleman said the two discoveries at opposite ends of the Rakhine Basin was a great result for the company. “These results are very encouraging for future exploration and appraisal activity, given the significant footprint we have in Myanmar, ” he said.
Coleman said Thalin-1A had proved a working petroleum system and a new play type different to that encountered at Shwe Yee Htun-1. “ These discoveries provide evidence of the high quality of offshore Myanmar as an exploration focus area,” he said.
Thalin-1A is located in the northern part of the Rakhine Basin approximately 60km west of the Daewoo-operated producing Shwe Field, which has onshore gas plant and pipeline gas export facilities.
With a 40% interest in AD-7, Woodside Energy (Myanmar) Pte Ltd, is the operator with respect to deepwater drilling. Daewoo International Corporation, with a 60% interest, is operator for all other operations. The AD-7 Block’s area was recently expanded north to the Myanmar maritime boundary.
The AD-7 Joint Venture has approved the acquisition of an additional 1200km2 of 3D seismic data over this area. The seismic survey is scheduled to start in March 2016.
