The facility, located in the Russian city of Omsk, is part of Gazprom Neft and has a designed processing capacity exceeding 21 million metric tons of crude oil annually, accounting for approximately 10% of Russia’s total oil refining output, according to Exilenova+.
The refinery produces several types of automotive gasoline, including AI-92, AI-95, and G-Drive 100, alongside Euro-5 diesel fuel, aviation kerosene, lubricants, and a wide range of petrochemical products.
Drone activity continues to be observed in the sky over Omsk.

Exilenova+ reported that the facility is also involved in supplying fuel and petroleum products to Russian occupation forces operating in Ukraine.
Following the reported strike, a large fire broke out in the industrial area, with flames continuing to spread as the drone threat warning remained in effect across Omsk.
Ukrainian OSINT community Cyber Boroshno reported that, for the first time in such long-range strikes deep inside Russian territory, the attack had lasted several hours and was still ongoing at the time of its report.

Amid the reported drone attack, parts of Omsk also experienced electricity disruptions. Residents of the Neftyaniki district reported street lighting failures, while those in the Amur neighborhood reported power outages, acording to ASTRA.
The outlet separately claimed that a thermal power plant in Omsk may have sustained damage.
The attack on Omsk coincided with reports of another major fire near Russia’s Ust-Luga port in the Leningrad region on November 11.
The fire followed reports of explosions and air defense activity amid a drone threat warning. Residents of the Kingisepp district shared footage purportedly showing a large blaze near Ust-Luga, one of Russia’s major maritime trading hubs on the Baltic Sea.
