Thailand’s PTT Exploration and Production Public Company Limited (PTTEP) has made its largest-ever gas discovery in Malaysia, the company announced in a press release on February 10.

PTTEP made the discovery through its wholly-owned subsidiary, PTTEP HK Offshore Limited (Malaysia) (PTTEP HKO), which successfully completed drilling the Lang Lebah-2 appraisal well under the Sarawak SK 410B Project.

PTTEP CEO Phongsthorn Thavisin said the appraisal drilling at Lang Lebah followed the discovery of gas at its first exploration well, Lang Lebah-1RDR2, in 2019.

The Lang Lebah-2 well was completed in mid-January 2021. It was drilled to a total depth of 4,320m, with more than 600m of proven net gas pay, indicating a larger reservoir than initially estimated. The well test shows a flow rate of 50 million cubic feet of gas per day and this result will accelerate the development plan for the project, the company statement said.

Phongsthorn said: “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 an increase of reserves for the company’s long-term growth.”

The Sarawak Project is located approximately 90km offshore of Sarawak. PTTEP HKO is the operator, with 42.5 per cent of participating interest, while KUFPEC Malaysia Ltd and Petronas Carigali hold 42.5 per cent and 15 per cent, respectively.

Apart from the Sarawak project, PTTEP’s portfolio in Malaysia comprises Block K, SK 309 and SK 311, and the Malaysia-Thailand Joint Development Area, which are production projects; Block H, which is a development project; and SK 417, SK 314A, SK 438, SK 405B, PM 407 and PM 415, which are exploration projects.

PTTEP has also undertaken joint investment with PTT in the MLNG Train 9 Project, an LNG liquefaction plant, through PTT Global LNG Company.
