Total E&P Myanmar will hold a 40 percent stake in the field, located in the Gulf of Martaban, while JX Nippon Oil & Gas Exploration (Myanmar) will hold 15 percent, it said in a statement.
PTTEP, the flagship in the upstream business of Thailand's top energy firm PTT Pcl, will remain the operator with a 45 percent stake. The deal is subject to approval from Myanmar's government.
The move is part of PTTEP's strategy to diversify risk. It plans to drill an exploration well in the block by the third quarter of 2013.
