Background

Following Russia's invasion of Ukraine, Exxon Mobil stated its intention to discontinue all its Russia operations and exit about $4 billion in assets, including the Sakhalin-1 oil and gas project. In March 2022, the company declared a force majeure for its Sakhalin-1 operations due to sanctions imposed on Russia which made it increasingly difficult to continue operations. The project's output collapsed following the force majeure, but full production was restored by January 2023.

In August 2022, the Russian government has ordered a freeze on any sale of Exxon's stake in Sakhalin-1 project, alongside similar bans on foreign-ownership transactions for other energy infrastructure assets. The announcement followed days after Exxon had started negotiations with a third party for a sale of its shares in Sakhalin-1.

In October 2022, President Putin has signed a decree that established a new Russian operator company for the Exxon-lead project. The new company, Sakhalin-1 LLC, is managed by a Rosneft subsidiary Sakhalinmorneftegaz-Shelf, which received investor's rights in the project. While SODECO (30%) and ONGC Videsh Limited (20%) maintained their shares in the new operator, Exxon's 30% stake was transferred to Sakhalinmorneftegaz-Shelf.

In December 2024, the Russian government has granted Exxon an extension until January 1, 2026, to divest its 30% stake in the project.

As of January 2024, ambiguity remains in regard to ownership of the project. While a Rosneft subsidiary officially owns the 30% stake formerly held by Exxon, the Russian government has also informally acknowledged ownership from the oil major, by granting Exxon the 1-year extension to sell its stake in the project.
