In the aftermath of the 24 August drone strike, the Syzran oil refinery in Russia’s Samara Oblast about 1,000 km from Ukraine is no longer operational due to the destruction of its most critical equipment. Russian Telegram channel Astra, citing sources in the emergency services, reported that the facility lost the AVT-6 primary processing unit, the L-35-6 secondary unit, and the pump station — all essential for continued refinery operations.

Core refinery units rendered inoperable

According to Astra, five drones exploded on site on 24 August, three of which directly struck key infrastructure. Five more drones were reportedly shot down on approach. No injuries were reported, as all 240 employees had sheltered during the attack.

Previous strike on Syzran refinery occurred weeks ago

The refinery, owned by Rosneft, is one of Samara Oblast’s largest oil-processing enterprises, producing a wide range of petroleum products and supplying fuel to central Russian oblasts and military units. Following earlier drone strikes on 15 August, the facility had already suffered major damage and had suspended crude oil intake and processing.

The 15 August attack struck the ELOU-AVT-6 unit, designed for desalting and primary crude oil distillation, and also damaged several storage tanks.

Systematic drone campaign deepens energy crisis

The refinery has also been targeted multiple times this year, with incidents in February and March causing fires. 

According to Reuters, Ukrainian drone strikes in August have disabled 17% of Russia’s oil refining capacity.

The situation has contributed to worsening fuel shortages across Russia and occupied Ukrainian territories, particularly in Crimea, Zabaykalsky Krai, Vladivostok, Buryatia, and Primorsky Krai.
