Background

In 2022, due to the war in Ukraine, Shell announced its intention to exit all equity partnerships held with Gazprom entities, including its 27.5% stake in the Sakhalin-II project.[6] In April 2023, Russia's government approved the sale of Shell's stake to Russian energy firm Novatek for 94.8 billion roubles ($1.16 billion).[7]
