Rosneft’s Ryazan Oil Refinery Shuts Down After Drone Attack, Industry Sources Say

By Reuters Sep. 10, 2026 Ryazan Oil Refinery. svtk44 (CC BY-SA 4.0) The Rosneft-owned Ryazan oil refinery has been forced to suspend operations following a Ukrainian drone strike on the facility last weekend, two industry sources told Reuters on Thursday. The sources said the oil refinery's main unit, CDU-6, as well as another primary unit, CDU-4, were shut down after the attack. CDU-6, which caught fire in the attack, can process 8 million metric tons of oil per year, or around 160,000 barrels per day, the sources said, accounting for almost half of the plant's capacity. CDU-4 can process 4 million tons of oil per year. Another primary unit, CDU-3, has been under maintenance since mid-May. The sources said repairs to the damaged units could take up to several weeks. The Ryazan oil refinery, which supplies Moscow with fuel, was also attacked by drones in May and July. Following the July attack, the facility suspended operations for around two or three weeks, the industry sources said. Ukraine began ramping up its attacks against Russian oil refineries and supply lines this spring in a bid to deprive the Kremlin of windfalls from surging oil prices. Drone strikes have halted or scaled back production at facilities that account for large shares of Russia's gasoline output.
