PTT Exploration and Production Public Company Limited (PTTEP) has announced a successful oil and gas discovery from the first exploration well, Sirung-1, in Block SK405B, off the coast of Sarawak, offshore Malaysia.

Phongsthorn Thavisin, PTTEP CEO, disclosed that PTTEP, through its subsidiary PTTEP Sarawak Oil Limited, commenced the drilling of Sirung-1 wildcat well in Block SK405B in January 2021. The well was drilled to a total depth of 2538 m where it encountered a significant oil and gas column of more than 100 m, in the clastic reservoirs. An appraisal well is scheduled in the near future to assess the upside resources.

“The Sirung-1 exploration well marks PTTEP’s third discovery offshore Malaysia following SK410B’s Lang Lebah and SK417’s Dokong. PTTEP also plans to explore nearby prospects in this PSC next year. The achievements have strengthened our investment base as we continue to expand our exploration horizon in Malaysia,” said Thavisin.

Block SK 405B is located in the shallow waters, approximately 137 km off the coast of Sarawak (Bintulu). PTTEP Sarawak Oil Limited is the operator with a 59.5% participating interest. MOECO Oil (SARAWAK) SDN.BHD. and PETRONAS Carigali Sdn. Bhd. hold 25.5% and 15% interests respectively.

Apart from the Sarawak SK405B, SK410B, SK314A, SK438, SK417, PM407 and PM415 are all still in the exploration stage. Major projects in PTTEP’s portfolio in Malaysia include the producing assets in Block K, SK309, SK311, the Rotan-Buloh field in Block H and the jointly operated gas fields with PETRONAS Carigali in the Malaysia–Thailand Joint Development Area. PTTEP is also a joint investor with PTT, through the PTT Global LNG Company, in the MLNG Train 9 Project, an LNG liquefaction plant in Sarawak.
