PTT Exploration and Production Public Company Limited (PTTEP) has announced PTTEP HK Offshore Limited, Malaysia Branch (PTTEP HKO), a wholly-owned subsidiary of PTTEP, has made a discovery of gas at the Lang Lebah-1RDR2, the first exploration well in Sarawak SK410B Project located in offshore Sarawak, Malaysia.
The project commenced in March 2019, the drilling of Lang Lebah-1RDR2 was targeted non-associated gas in the primary target of the Middle Miocene cycle IV/V carbonate reservoir and undertaken to a total depth of 3,810 meters. The well encountered 252 meters of net gas pay, indicating a multi-TCF 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 barrel of condensate per day (BCPD) through 40/64-inch choke size. The drilling result of the Lang Lebah-1RDR2 is historically PTTEP’s largest discovery. This affirms PTTEP’s strategy in organically growing reserves from exploration activities. The discovery will require further drilling to confirm the upside potential.
Sarawak SK410B Project is located in the shallow waters, approximately 90 kilometers offshore Sarawak, with the acreages of approximately 1,870 square kilometers. The consortium consists of PTTEP HKO, KUFPEC, and PETRONAS Carigali Sdn. Bhd. with participating interests of 42.5%, 42.5% and 15% respectively.
