PTT Exploration and Production Public Co. Ltd. (PTTEP) subsidiary PTTEP HK Offshore Ltd. (PTTEP HKO) discovered gas at Kulintang-1, the first exploration well in Block SK438 in shallow waters, about 108 km off the coast of Sarawak (Bintulu), Malaysia. The company plans to drill another exploration well in the block in this year’s second quarter, it said in a May 19 statement.
Kulintang-1 was drilled to 2,238 m total depth in April. The well encountered gas in the Oligocene to Middle Miocene sandstone reservoirs, which has not been fully evaluated before, said partner Petronas in a separate statement.
The gas discovery “proves further potential of sweet gas in the [Balingian] province, especially in the deeper Oligocene play,” said Petronas Senior Vice-Pres. of Malaysia Petroleum Management, Mohamed Firouz Asnan.
In March, PTTEP discovered oil and gas in the Sirung-1 wildcat exploration well in Block SK405B, also in the Balingian Province (OGJ Online, Mar. 30, 2021).
PTEEP HKO is operator of Block SK438 with 80% participating interest. Petronas Carigali Sdn. Bhd. holds 20%.
