On September 7, ExxonMobil Holdings Corp. (NYSE:XOM) announced that it would raise its stake in the Papua LNG project from 28.7 % to 34.1 % and assume operatorship, while TotalEnergies SE would trim its share to 20 %. The change follows a redesign that lowered the estimated capital cost from roughly $18 B to about $14 B.

The Papua LNG development sits in Papua New Guinea’s Gulf Province and is slated to produce 5.6 million tonnes of liquefied natural gas (LNG) annually from the Elk and Antelope fields. The project will include gas‑processing facilities, a pipeline that links the fields to a liquefaction site, and export infrastructure near Port Moresby. ExxonMobil said the final investment decision (FID) is targeted for the fourth quarter of 2026.

Transferring operatorship to ExxonMobil is intended to sync the project’s construction and operations with the nearby PNG LNG plant, which the company already runs. According to the company’s disclosure, the shared infrastructure and local experience should streamline coordination during the build‑out and reduce operational risk.

TotalEnergies’ cost‑reduction effort involved a redesign of the plant and a rebidding of contractors. The new estimate represents a 22 % drop from the previous $18 B figure. The revised budget is aimed at keeping the project viable even if LNG prices soften. In addition, TotalEnergies and the Papua New Guinea government amended the 2019 gas agreement to reflect the lower capital cost and to preserve the state’s fiscal interests.

Commercial arrangements have also progressed. TotalEnergies and PNG’s state‑related entities formed a marketing joint venture that will purchase 2.4 million tonnes of LNG annually. The company also signed a heads‑of‑agreement to buy 1.5 million tonnes per year for its global portfolio. While the heads‑of‑agreement does not set final pricing or financing terms, it signals intent to secure long‑term sales.

The project still requires several approvals. Engineering, procurement and construction tenders are complete, but contract recommendations must receive partner approval. Inflation, contractor performance and construction delays could erode the projected savings. The operatorship shift also increases ExxonMobil’s exposure to capital requirements and potential overruns.

Hedge‑fund activity around the deal has risen modestly. Insider Monkey’s database shows 96 hedge funds holding ExxonMobil shares at the end of the second quarter of 2026, up from 94 three months earlier.

The next milestones for Papua LNG are the final approval of construction contracts, the binding of sales agreements, and the FID itself. The project’s economics will depend on the timing of first production, operating costs, shipping economics and the final terms of the marketing agreements.

In summary, the lower capital cost makes Papua LNG a more attractive investment, and the operatorship transfer offers potential operational synergies. However, the project’s viability will ultimately hinge on securing the remaining commercial, regulatory and financing commitments before the scheduled FID in late 2026.
