The Kuibyshev refinery, part of Rosneft’s Samara group, became the fifth major Russian oil plant to halt operations after a drone strike, Reuters reported on August 29, citing industry sources.
Both primary oil processing units at the 7 million-ton-per-year facility, each handling 10,000 tons per day, were damaged. Some secondary processing units were also affected.
Earlier in August, Novokuibyshevsky refinery, Saratov refinery, Lukoil’s Volgograd refinery, and Syzran refinery all suspended operations following drone attacks.

Additionally, about half of the Ryazan refinery, Rosneft’s largest, was shut down on August 2, while the status of the Novoshakhtinsky refinery remains unclear after a five-day fire.
Despite the disruptions, Russian oil output has seen only a modest impact. Industry sources told Reuters that fuel production fell by just 5% in August, as the reduction at damaged facilities was offset by increased throughput at operational refineries.
Previously, it was reported that drone strikes have already disabled at least 10 Russian refineries this month, cutting facilities that account for roughly 17% of the country’s processing capacity—around 1.1 million barrels per day. Despite these disruptions, Russia has managed to boost oil exports by an estimated 200,000 barrels per day, offsetting some of the domestic production losses.
