TotalEnergies Buys 30% Stakes in Malaysia’s Lang Lebah and B14 Gas Fields
TotalEnergies has signed agreements to acquire 30% operated interests in two offshore gas fields off Sarawak, Malaysia — Lang Lebah and B14 — in deals with PETRONAS Carigali Sdn Bhd (PCSB), Thailand’s PTTEP and Kuwait’s KUFPEC. The French major announced the transactions on Monday, saying the two fields will be developed as a single integrated project to supply the existing Malaysia LNG liquefaction complex. The deals are subject to regulatory approval.
A new 30-25-25-20 ownership split
Once the transactions close, TotalEnergies will hold a 30% operated interest in both Lang Lebah and B14, with PTTEP and KUFPEC each holding 25% and PCSB, Petronas’s upstream arm, retaining 20%. TotalEnergies described Lang Lebah as one of Malaysia’s largest offshore gas discoveries. The company put the combined resource base of the two fields at more than 6.5 trillion cubic feet of gas, equivalent to more than 1 billion barrels of oil equivalent, with a planned production plateau of about 10 billion cubic meters a year.
Building a new gas hub for Sarawak
"The development of Lang Lebah and B14 resources will allow the creation of another large-scale gas hub in Malaysia," TotalEnergies chairman and chief executive Patrick Pouyanné said in the company’s announcement. The gas is earmarked to feed Petronas’s Malaysia LNG complex at Bintulu, one of the world’s longest-running LNG export sites, as the state operator looks to backfill supply for its liquefaction trains with new offshore discoveries.
TotalEnergies deepens a young Malaysian position
TotalEnergies’ position in Malaysia is relatively recent: it took over SapuraOMV’s upstream assets in 2024, picking up operated stakes in blocks including SK408 and SK310 off Sarawak. In 2025 it expanded its partnership with Petronas further, taking new interests in several additional offshore blocks, including a 50% operated stake in blocks SK301b and SK313, where gas discoveries exceeding 4 trillion cubic feet have been made and which are also intended to supply Malaysia LNG from 2030. TotalEnergies and Petronas have also moved into decarbonization infrastructure together: in October, the two companies signed a joint-venture agreement with Mitsui for Malaysia’s Southern CCS Hub, a project to store carbon dioxide from industrial customers in the region.
Competing majors chase the same gas basin
TotalEnergies is not alone in expanding around Sarawak’s gas basins. Eni has separately set up Searah, a jointly owned upstream company with Petronas covering exploration and production interests in both Malaysia and Indonesia, underlining how international majors are positioning for a new wave of Southeast Asian gas supply as Asian LNG demand grows and existing fields in the region mature. TotalEnergies’ broader LNG and refining business was already running strong in the third quarter, as shown in its Q3 2026 results.
