Exxon steps in as operator, TotalEnergies reshapes its exposure
TotalEnergies has agreed to transfer operatorship of the Papua LNG project in Papua New Guinea to ExxonMobil, which already runs the neighbouring PNG LNG development. This change is designed to create tighter operational alignment between the two projects. It also supports more efficient execution as Papua LNG moves towards sanction.
At the same time, TotalEnergies will sell a 9.1% interest in the project to its existing partners, following the Papua New Guinea state’s back-in, and will retain a 20% stake. According to the company’s announcement, ExxonMobil will hold about 34.1% once the deal completes. Santos will own 21%, ENEOS Xplora 2.4%, and state entities Kumul Petroleum and MRDC will have a combined 22.5%.
The French group will keep its current LNG offtake share, giving it access to roughly 1.5 million tonnes per year for its global portfolio, despite the lowered equity exposure. The shift in operatorship is framed by the partners as a way to cut risk and improve delivery. ExxonMobil, as operator of PNG LNG, brings established infrastructure, relationships and operational experience in country.
An ExxonMobil spokesperson said the combined operatorship is expected to strengthen project alignment, improve execution efficiency and support the development of Papua New Guinea’s LNG resources. For investors, the analyst takeaway is clear: Papua LNG moves from being a stranded growth option to a more bankable, portfolio-integrated project.
Santos has also moved quickly to deepen its exposure. The Australian producer agreed to acquire an additional 3.3% participating interest in Papua LNG for about US$189 million. That will lift its share to 21% once the state back-in processes are complete. Santos expects the higher stake to increase its equity LNG production from Papua LNG by around 19%, to approximately 1.2 million tonnes per year. The acquisition remains conditional on regulatory approvals and on Papua LNG reaching a final investment decision, which Santos continues to guide for the fourth quarter of 2026.
What does the Papua LNG stake reshuffle mean for Asian gas demand?
Papua LNG is designed to develop the Elk and Antelope gas fields in Papua New Guinea’s Gulf Province, with planned output of 5.6 million tonnes of LNG per year. Most volumes are expected to go to Asian buyers, positioning the project close to major demand centres in North-East and South-East Asia. As a result, the restructuring of the Papua LNG stake and operatorship has direct implications for regional supply portfolios. Asian utilities looking to diversify away from Atlantic-basin cargoes will be watching closely.
TotalEnergies said it has completed the tendering process for major engineering, procurement and construction contracts, with agreements now awaiting partner approval. Project cost discipline has been central to recent decisions. Company data indicate that around US$4 billion of savings have been achieved since 2024 through renewed bidding processes and design changes, bringing the estimated capital expenditure down to about US$14 billion. This cost reset helps the partners defend project economics in a more volatile LNG price environment.
Crucially, key contractual and commercial matters with Papua New Guinea’s government have been settled. Amendments to the gas agreement — reported by Energy Intelligence and confirmed by the Prime Minister — remove one of the main execution hurdles. They mark a significant step towards final investment decision. Government statements and local reporting indicate that the revised arrangements also clarify back-in rights and potential additional equity options for the state.
In addition, the partners and state-owned Kumul Petroleum have set up an LNG marketing joint venture that will manage sales for 2.4 million tonnes per year of the planned output. This structure gives the state a more direct role in marketing while anchoring off-take discussions.
For Papua New Guinea, Papua LNG remains a major potential source of foreign investment, export earnings and fiscal revenue. By contrast, for international investors the project offers exposure to a geographically advantaged supply source that can feed Asian demand without long-haul shipping. The combination of lower capex, resolved state agreements and a stronger operator in ExxonMobil narrows the list of remaining risks to market conditions and project financing.
The next few quarters will be critical. Investors should watch progress on EPC contract approvals, LNG marketing commitments and the formal final investment decision targeted for late 2026. If the partners reach sanction on schedule, Papua LNG could start to reshape regional LNG trade flows and lift Santos’ production profile, while giving TotalEnergies and ExxonMobil another scalable Asian-focused growth platform.
Quick answers
TotalEnergies is selling a 9.1% interest to its existing partners to reduce its equity exposure while retaining a 20% stake and its full LNG offtake share of roughly 1.5 million tonnes per year. The move also facilitates the transfer of operatorship to ExxonMobil, which is designed to improve project alignment and execution.
ExxonMobil will hold approximately 34.1% and Santos will own 21% once the transaction and state back-in processes are complete. Santos paid about US$189 million to acquire the additional 3.3% participating interest.
The partners are guiding for a final investment decision in the fourth quarter of 2026. The project targets 5.6 million tonnes of LNG per year from the Elk and Antelope gas fields, with estimated capital expenditure of around US$14 billion.
