A drone strike forced Rosneft's Kuibyshev refinery to stop processing crude on June 10 after the attack damaged equipment and sparked a fire, Reuters reported Wednesday, citing two industry sources.
Damage from the strike shut down both of the refinery's main crude processing units, CDU-4 and CDU-5, which can each handle about 10,000 metric tons, or 73,000 barrels, of crude per day, according to industry sources.
Recent peace efforts between Russia and Ukraine have delivered little progress, while Kyiv has stepped up attacks on Russian energy sites, the report said.
Kuibyshev is one of three refineries in Rosneft's Samara refining network, alongside the Novokuibyshevsk and Syzran plants. Authorities also reported another drone attack in the Samara region early Wednesday.
Earlier attacks have already disrupted the hub. Syzran has remained shut since equipment was damaged on May 21, while Novokuibyshevsk resumed operations only partially after suspending processing following an April 18 strike, market sources said.
During 2024, the Kuibyshev refinery ran about 4.7 million mt of crude, or roughly 94,400 b/d, and supplied 800,000 mt of gasoline, 1.4 million mt of diesel and 1.3 million mt of fuel oil, industry sources said.
Rosneft didn't immediately respond to' request for comment.
