As both nations grapple with Western sanctions, Iran and Russia are doubling down on energy cooperation, with Moscow’s major oil companies now active in seven Iranian fields and negotiations underway to expand their footprint, a top Iranian oil official confirmed this week.
Reza Aghebati, manager of engineering and development at the National Iranian Oil Company (NIOC), told the Shana news agency that Russian firms have already invested in fields including Aban, Paydar-e Gharb, Paydar-e Shargh, Dalpari, Cheshmeh Khosh, Shadegan, and Kupal. Two of these—Paydar-e Gharb and Aban—are shared reservoirs, adding a layer of strategic importance to the collaboration.
"Given the clear willingness of Russian companies to increase their investment, we are actively working to remove hurdles and expand cooperation in the development of our oil and gas fields," Aghebati said. He expressed optimism that the Russian share in both development and production would rise in the near future.
The remarks follow a visit to Tehran last week by Russia’s Energy Minister, Sergey Tsivilyov, who met with Iran’s Oil Minister, Mohsen Paknejad. The two sides reviewed progress on 146 cooperation items agreed upon during the 19th session of the Iran-Russia Joint Economic Committee, with a focus on accelerating field development projects and ramping up gas trade.
For Tehran, the deepening partnership offers access to technology and financing that have become scarce under U.S. sanctions. For Moscow, it provides a foothold in one of the world’s largest proven reserves, as Russia seeks new energy allies and markets in the face of its own widening isolation. The move signals a broader realignment, as both producer giants look to consolidate regional energy influence and bypass dollar-based trade mechanisms.
