PTT Exploration and Production Public Co. Ltd (PTTEP) has announced that its subsidiary PTTEP HK Offshore Limited (Malaysia Branch) has made a discovery of gas at the Lang Lebah-1RDR2, the first exploration well in Sarawak SK410B Project located in offshore Sarawak, Malaysia.

After commencing in March 2019, drilling of Lang Lebah-1RDR2 was targeted at non-associated gas in the primary target of the Middle Miocene cycle IV/V carbonate reservoir and undertaken to a total depth of 3810 m. The well encountered 252 m of net gas pay, indicating a multi-trillion ft3 gas discovery. The well was tested in carbonate main target reservoir with a completion-constrained (2-7/8” tubing) rate of 41.3 MMSCFD and 246 bpd of condensate through 40/64-in. choke size.

The drilling result of the Lang Lebah-1RDR2 is PTTEP’s largest ever discovery. The discovery will require further drilling to confirm upside potential.

Sarawak SK410B Project is located in the shallow waters, approximately 90 km offshore Sarawak, with the acreages of approximately 1870 km2. The consortium consists of PTTEP HKO (the Operator), KUFPEC and PETRONAS Carigali Sdn. Bhd. with participating interests of 42.5%, 42.5% and 15% respectively.
