TotalEnergies Cuts Papua LNG Cost to About $14 Billion and Hands Operatorship to ExxonMobil

TotalEnergies said Sept. 7 that it has cut the estimated capital cost of Papua LNG to about $14 billion and agreed to transfer operatorship of the project to ExxonMobil, two changes the French energy group says move the long-delayed development materially closer to a final investment decision.

The revised budget is roughly $4 billion below the level discussed in 2024. TotalEnergies said the reduction came from project design optimization and from rebidding engineering, procurement and construction packages to a broader group of Asian contractors. At the same time, the partners decided ExxonMobil should run the project so it can be developed in closer coordination with PNG LNG, the neighboring export venture ExxonMobil already operates in Papua New Guinea.

Those steps matter because Papua LNG is not a small tie-back or an incremental debottlenecking project. It is a major gas development centered on the Elk and Antelope fields in Gulf Province, with gas processing facilities, a pipeline to the coast and liquefaction infrastructure planned near Port Moresby. TotalEnergies said the project is designed to produce 5.6 million tonnes of LNG a year, mostly for Asian buyers, making budget discipline and operating efficiency central to whether the project reaches sanction on acceptable returns.

Lower costs and a new operator change the project economics

In its Sept. 7 announcement, TotalEnergies said the engineering and contracting process had reached a point where contract-award recommendations were ready for co-venturer approval. That milestone helped the company put a more definite number on the expected capital bill, which it now places at around $14 billion.

Management attributed the lower figure to two main factors. One was project redesign, including an alternative upstream condensate scheme designed to work in synergy with PNG LNG. The other was a fresh round of EPC bidding with an enlarged pool of Asian contractors. Together, those efforts cut enough cost to bring the headline budget down by close to $4 billion from the 2024 level, giving the project a better chance of generating acceptable economics through the cycle rather than only under strong LNG pricing conditions.

Handing operatorship to ExxonMobil is the other major shift. ExxonMobil already operates PNG LNG, so the transfer is intended to maximize construction and operating synergies between the two developments. TotalEnergies and ExxonMobil said they will work through a safe transition while keeping existing commitments to Papua New Guinea’s authorities and other stakeholders in place. For investors, the logic is straightforward: one operator overseeing adjacent LNG systems can potentially simplify interfaces, reduce duplication and improve execution on a project whose scale leaves little room for avoidable cost overruns.

TotalEnergies stopped short of saying Papua LNG has reached final investment decision status. Instead, the company framed the announcement as a set of decisive steps toward that point. That distinction matters. The lower budget and operator change improve the project’s positioning, but they do not themselves amount to a formal board-sanction decision. Papua LNG has been discussed for years, and this latest update is best read as a meaningful de-risking event rather than the finish line.

Farm-down reshapes ownership while TotalEnergies keeps LNG offtake exposure

The operator switch is tied to a reshaping of the ownership structure. TotalEnergies said it will sell a 9.1% project interest, after taking into account Kumul Petroleum’s back-in right, to the other Papua LNG partners in proportion to their existing stakes. Once that process is complete, TotalEnergies will retain a 20% interest in the venture while ExxonMobil will hold 34.1% and become operator.

The rest of the equity will be spread across Santos at 21.0%, ENEOS Xplora at 2.4%, and Kumul Petroleum Holdings Limited together with MRDC at 22.5%, according to TotalEnergies. In other words, the company is reducing its direct ownership but not walking away from the project. It is effectively giving more equity and operating control to ExxonMobil while keeping a meaningful financial position in Papua LNG.

That smaller equity share does not mean a proportionate retreat from the marketing side. TotalEnergies said it will maintain its LNG offtake share from the project even after the farm-down. It also announced the creation of an LNG marketing joint venture with PNG state-related entities represented by Kumul Petroleum Holdings Limited. That venture will jointly commercialize 2.4 million tonnes a year from Papua LNG’s planned 5.6 million tonnes a year of output, a structure TotalEnergies said will support project financing.

On top of that, the company said it has executed a heads of agreement under which TotalEnergies, acting as buyer, will access 1.5 million tonnes a year of LNG from the marketing joint venture for its own global portfolio. That is important strategically because it helps explain why the company is willing to cede operatorship and dilute its equity while still calling the new arrangements a value-creating step. Even at 20% ownership, TotalEnergies retains a route to substantial LNG volumes that fit its broader portfolio and Asian market strategy.

The announcement also underscores how PNG state participation remains part of the overall balance. The reference to Kumul Petroleum’s back-in right and the joint marketing venture shows that this is not simply a private-sector reshuffle among international oil and gas companies. Papua New Guinea’s state-related entities are still embedded in the structure, both as equity participants and as commercial stakeholders in the eventual LNG sales program.

Amended gas terms and remaining approvals keep the focus on FID

Several other pieces moved into place alongside the cost reduction and the operatorship change. TotalEnergies said the Papua LNG partners finalized an amended Gas Agreement with the government of Papua New Guinea. The original agreement was signed in 2019, and the company said the updated version reflects the revised budget and optimization work while aiming to preserve the state’s long-term fiscal interests and keep the project robust even in a lower-price environment.

That amended agreement matters because large LNG developments depend not only on engineering readiness but also on fiscal stability and commercial clarity. A lower capital estimate helps, yet lenders and partners still need confidence that the overall framework can support the project through construction and into operations. By pairing a slimmer budget with updated gas terms and new marketing arrangements, TotalEnergies is trying to show that Papua LNG is approaching sanction with more pieces locked in than it had before.

Even so, not every risk has disappeared. Final Investment Decision still needs to be taken, and contract-award recommendations still require co-venturer approval. Major LNG developments also remain exposed to execution risk, commodity-price swings, contractor performance and geopolitical or regulatory changes over a multiyear build cycle. The Sept. 7 package addresses some of those concerns, particularly on cost and project configuration, but it does not erase them.

What has changed is the balance of evidence around whether Papua LNG can move ahead in a more competitive form. A budget of around $14 billion is materially easier to finance and defend than the higher figure discussed earlier. Letting ExxonMobil integrate development with PNG LNG may also appeal to partners who value operational continuity over operator prestige. Meanwhile, TotalEnergies can still point to a meaningful retained stake, preserved offtake access and a marketing structure aligned with its global LNG ambitions.

For Papua New Guinea, the update keeps alive one of the country’s most significant prospective resource investments, with promised benefits ranging from employment and local business activity to expanded national involvement in gas commercialization. For the companies involved, the immediate next milestone is simpler and more concrete: turning these contractual, commercial and ownership changes into a formal final investment decision. Until that happens, Papua LNG is closer to sanction, but not there yet.
