MOSCOW, Sept 21 (Reuters) – Russia’s major Moscow refinery, owned by Gazprom Neft, has halted crude oil ‌processing after fires broke out at its primary ‌crude distillation units following a Ukrainian drone attack on September 20, ​three industry sources said.

Moscow Mayor Sergei Sobyanin said on Telegram on Sunday morning that an industrial facility on the refinery’s premises had been damaged during a drone raid ‌on the Russian capital.

The ⁠sources told Reuters on Monday that both of the refinery’s primary crude distillation units ⁠caught fire after drones crashed onto the site and that it could take several weeks to repair the damage ​and ​restore operations.

Gazprom Neft did not ​immediately respond to a ‌Reuters request for comment.

The refinery’s AVT-6 unit has a capacity of 21,400 metric tons per day, representing 53% of its total capacity, while the EURO+ combined crude processing facility has a capacity of 18,800 tons per ‌day, making up the remaining 47%.

Fuel ​produced by the Moscow refinery ​has not been ​offered for sale on the St. Petersburg ‌International Mercantile Exchange since September ​21.

The sources said ​the refinery processed 11.6 million tons of crude oil in 2024, some 230,000 barrels per day, and ​produced 2.9 ‌million tons of gasoline, 3.2 million tons of diesel ​and 1.3 million tons of bitumen.
