Oil refining in Russia has fallen to 4.69 million barrels per day, the lowest level since 2009, following repeated Ukrainian strikes on energy infrastructure, Bloomberg reports.
Ukrainian forces have intensified attacks on Russian oil facilities, reaching their highest frequency since December 2025, the outlet says.
In April 2026 alone, Ukrainian drones targeted oil refineries, sea terminals and pipeline infrastructure at least 21 times.
At least nine refineries were hit, with five reportedly halting operations either fully or partially.
Since mid-April, four attacks have targeted an oil refinery and its marine terminal in Tuapse, in Russia’s Krasnodar region. The latest strike was reported on May 1.
In late April, Ukrainian forces carried out two consecutive days of drone strikes on an oil pumping station in Perm, owned by ‘Transneft’, and an oil refinery operated by ‘Lukoil’.
The Ukrainian government says the strikes aim to reduce Russia’s export capacity and limit funding for the war.
The Russian government describes the attacks as “terrorist acts.”
