Russia's Yaroslavl refinery halts crude processing after Ukrainian drone strike - Reuters

The Sept. 17 strike damaged the refinery's AVT-3 primary crude distillation unit, which can process 17,140 metric tons per day and accounts for about 40% of the plant's total processing capacity, according to Reuters.

Another primary distillation unit, AVT-4, which accounts for 33% of the refinery's capacity, was already undergoing repairs after being damaged in an earlier Ukrainian drone strike on Aug. 28.

The plant's remaining primary distillation unit, AT-4, accounts for 27% of its total capacity.

Market participants told Reuters that fuel produced by the Yaroslavl refinery was not offered for sale on Russia's domestic commodity exchange on Sept. 17.

The Slavneft-YANOS refinery is located about 250 kilometers (155 miles) northeast of Moscow and has a processing capacity of about 300,000 barrels per day, or 15 million metric tons of crude oil per year.

In 2024, the refinery processed 14.9 million metric tons of crude, producing 2.6 million tons of gasoline, 4 million tons of diesel and 4.7 million tons of fuel oil, according to industry sources cited by Reuters.

Ukraine's General Staff confirmed striking the refinery overnight on Sept. 17 and reported a fire at the AVT-3 unit. President Volodymyr Zelenskyy also confirmed the strike.

Yaroslavl regional Governor Mikhail Yevrayev said 65 drones had been downed during the attack and acknowledged that the refinery had sustained damage and fires. He reported no casualties.

The refinery is owned by Slavneft, which is jointly controlled by Russian oil companies Rosneft and Gazprom Neft.
