PTTEP confirms its largest-ever gas discovery offshore Malaysia

PTT Exploration and Production Public Co. Ltd. (PTTEP), through subsidiary PTTEP HK Offshore Ltd. (Malaysia Branch), confirmed its largest-ever gas discovery with the Lang Lehah-2 appraisal well in the Sarawak SK 410B project offshore Malaysia.

The appraisal followed the gas discovery of its first exploration well, Lang Lebah-1RDR2, in 2019 (OGJ Online, June 28, 2019). Lang Lebah-2 was completed in mid-January 2021. Drilled to 4,320 m TD, the 600 m of net gas pay indicates a larger reservoir than the initial estimate. The well test shows a flow rate of 50 MMcfd of gas. The result will accelerate the development plan for the project.

Sarawak SK 410B lies 90 km offshore Sarawak, Malaysia. PTTEP HKO is operator with 42.5% participating interest. Partners are KUFPEC Malaysia (SK-410B) Ltd. (42.5%) and Petronas Carigali Sdn. Bhd. (15%).
