Bangkok, February 10, 2021 – PTT Exploration and Production Public Company Limited (PTTEP), through a wholly-owned subsidiary PTTEP HK Offshore Limited (Malaysia Branch) or PTTEP HKO, successfully completed the Lang Lebah-2 appraisal well in the Sarawak SK 410B Project. The drilling result registers a new record for PTTEP’s largest gas discovery.

Mr. Phongsthorn Thavisin, PTTEP Chief Executive Officer, disclosed that the appraisal drilling at Lang Lebah structure followed the gas discovery of its first exploration well, Lang Lebah-1RDR2, in 2019. The appraisal well Lang Lebah-2 was completed in mid-January 2021. It was drilled to a total depth of 4,320 meters with proven over 600 meters of net gas pay, indicating a larger reservoir than the initial estimate. The well test shows a flow rate of 50 million cubic feet of gas per day (MMSCFD). The result will accelerate the development plan for the project.

“We are delighted to confirm the largest-ever gas discovery by PTTEP. The experience and expertise from our operations in the Gulf of Thailand and overseas have contributed to this achievement. The Lang Lebah gas discovery strengthens PTTEP’s investment base in Malaysia and demonstrates that our ‘Execute strategy’ has translated into reserves increase for the company’s long-term growth,” said PTTEP CEO.
