Here are the 10 largest gas discoveries in Southeast Asia in the past 30 years.
- The Abadi gas field in Indonesia. The deepwater field has 18 TCF of gas in place and was discovered by Inpex in 2000. Inpex, along with new partners Petronas and Pertamina, plans to complete the Abadi project that will include the construction of an onshore LNG plant and carbon capture and storage.
- The Layaran-1 well in Indonesia. The discovery well was drilled by Mubadala in 2023. Test data show 6 TCF of gas in place.
- The Geng-North 1 well in Indonesia. Eni drilled this discovery well in 2023. The gas in place is said to be 5 TCF.
- The Kawasari Field in Sarawak, Malaysia, was discovered by Petronas in 2011 in Block SK 316 offshore Sarawak. The field holds an estimated 2 trillion cubic feet (TCF) of gas in place. Initial production reached about 200 million standard cubic feet per day (MMSCFD). Under its gas sales arrangements, Kawasari is contracted to supply up to 545 MMSCFD to the Petronas LNG Complex in Bintulu as well as the domestic market.
- The Marjoram/Rosmari development project in Sarawak, Malaysia. Shell discovered the deepwater Marjoram and Rosmari sour gas fields in 2014. The two fields contain 2 TCF of combined gas in place.
- The Jerun Field in Sarawak, Malaysia. The Jerun gas field was discovered by SapuraOMV Upstream with its partners, Sarawak Shell and Petronas Carigali in 2016. Located in Block SK 408 in offshore Sarawak, the field contains 1.5 TCF of gas.
- Block B Gas development in Vietnam. This huge integrated gas and power project involves Vietnam Oil and Gas Group, PetroVietnam Exploration Production Corporation Limited, PetroVietnam Gas Joint Stock Corporation, PTTEP of Thailand, and Mitsui of Japan. The field is scheduled to start delivering 490 MMSCFD of gas to four power plants in southern Vietnam by a subsea pipeline in 2026.
- Ca Voi Xanh field in Vietnam. The Cai Voi Xanh field was discovered by ExxonMobil and PetroVietnam in 2011. This is one of Vietnam’s two largest gas discoveries, with a gross gas volume estimated at 7 TCF (including CO2 and other inert gas). First gas production is not expected earlier than 2030. The gas will be delivered to power onshore power plants via an 88 Km subsea pipeline.
- B14 gas field in Sarawak, Malaysia. Located in block SK310 offshore of Sarawak, the gas field was discovered in 2013 by SapuraOMV along with its partners Petronas and Mitsubishi. With 1.3 TCF of gas in place, production is scheduled to begin in 2028.
- BIGST Cluster in Malaysia. The cluster, comprised of five undeveloped high-CO2 gas fields – the Bujang, Inas, Guling, Sepat, and Tujoh fields – was awarded to Petronas Carigali and JX Nippon Oil and Gas Corporation. The BIGST development will include carbon capture and storage, making it the first high-CO2 gas development in peninsular Malaysia that incorporates CCS. Production will start in 2026.
