TotalEnergies has signed agreements with Petronas Carigali, Thailand’s PTTEP and Kuwait’s KUFPEC to acquire a 30 percent operated interest in the Lang Lebah and B14 gas fields offshore Sarawak, Malaysia, the company announced on Monday. The signing ceremony was held in Abu Dhabi on November 1, alongside the ADIPEC conference.
On completion, which remains subject to regulatory approvals, TotalEnergies will operate both fields with a 30 percent interest, alongside PTTEP at 25 percent, KUFPEC at 25 percent and Petronas Carigali retaining 20 percent. The two fields, held under separate production sharing contracts (SK410B for Lang Lebah and SK310 for B14), will be developed as a single integrated project.
TotalEnergies estimates the combined development will unlock more than 6.5 trillion cubic feet of gas resources, equivalent to more than 1 billion barrels of oil equivalent, supplying the existing Malaysia LNG liquefaction plant at a production plateau of around 10 billion cubic metres a year. Lang Lebah, about 90 kilometres off Miri, is one of Malaysia’s largest offshore gas discoveries.
The deal extends a deliberate build-up. TotalEnergies, present in Malaysia since 1985, became the country’s third-largest gas producer through its 2024 acquisition of SapuraOMV Upstream and expanded its Petronas partnership in 2025. Chief executive Patrick Pouyanne framed Lang Lebah and B14 as another large-scale Malaysian gas hub built on shared infrastructure.
Neither side disclosed a purchase price or a development budget. What changed hands is control: Petronas keeps a minority stake and the LNG plant keeps its feedstock, while operatorship, and with it the development timetable and capital programme, passes to a consortium led by a French major and backed by two other state oil companies.
