Russia's Novokuibyshevsk oil refinery halts operations after drone attacks
Primary oil processing at Russia's Novokuibyshevsk refinery, which is operated by the Rosneft oil company, has been halted since August 2 following a Ukrainian drone attack last week, two industry sources said.
That was the first time a major Russian refinery had been attacked by a drone since March 2025.
It came after U.S. President Donald Trump last Monday set a 10 to 12 day deadline for Moscow to agree on a ceasefire with Kiev or face consequences, underscoring his frustration over the continuing 3.5-yr conflict.
U.S. special envoy Steve Witkoff is expected to travel to Russia this week after his current visit in Israel.
The refining capacity of Novokuibyshevsk is 8.3 metric MMtpy of oil (or some 160,000 bpd). Rosneft did not respond immediately to a request for comment.
According to the sources, the attack damaged the main primary oil refining unit CDU-11 at the Novokuibyshevsk refinery. The refinery has two primary units: CDU-11 with a capacity of 18,900 metric tpd, and CDU-9 with a capacity of 4,700 tpd.
The refinery planned to stop CDU-9 for a major scheduled maintenance from August to early September.
According to the sources, the Novokuibyshevsk oil refinery was recently processing about 18,000 tpd of crude oil.
Last year, the refinery processed 5.74 MMt of crude oil, produced 1.10 MMt of motor gasoline, 1.64 MMt of diesel fuel, and 1.27 MMt of fuel oil, according to industry sources.
