The well, which has been drilled to a depth of 4,820 meters, encountered 40 meters of net gas pay in a high-quality reservoir, and preliminary tests confirmed good reservoir quality, permeability and well production deliverability.

The company said that the successful completion of the appraisal is an important step in confirming a commercial project.

Previously, the Shwe Yee Htun-1 and Pyi Thit-1 gas discoveries have been made in the A6 block in 2016 and 2017. The cumulated resources in the block are evaluated in the range of 2Tcf to 3Tcf.

Total president of exploration and production Arnaud Breuillac said: “This new discovery on A6 block is a major step towards unlocking new gas reserves in an area closely located to the fast growing regional markets.

“Total’s track record of Myanmar’s Yadana gas field exploitation is a key asset to lead these discoveries to commercial development.”

Total holds a 40% interest in A6 block, technical joint operator for exploration and appraisal operations Woodside Energy 40%, and joint operator MPRL E&P 20% interest.

According to joint venture agreements, Total will take over operatorship in the development phase.

Total E&P Myanmar (TEPM) is the operator of the M5 and M6 blocks on the Yadana offshore gas field, with a 31.2% interest. These have gone on stream in 1998.

Production from M5 and M6 blocks caters to half of Myanmar’s gas consumption and 12% of gas consumed by neighboring Thailand.

TEPM began production from the Badamyar project in 2017, enabling extension of the Yadana gas field’s production plateau beyond 2020.

Total began gas exploration operations in Myanmar in 1992, when the company began developing the Yadana gas field to supply markets in Myanmar and Thailand.

The company has also taken up exploration at other blocks.
