A Ukrainian drone strike on the Orsknefteorgsintez refinery in Russia's Orenburg Oblast has caused a complete shutdown of operations, with repairs expected to take up to six months due to imported equipment and sanctions, according to the local governor.
The prolonged shutdown of a significant Russian oil refinery due to Ukrainian strikes highlights the growing impact of Ukraine's long-range attacks on Russia's energy sector and economy, potentially leading to domestic fuel shortages and increased pressure on the Kremlin.
A Russian oil refinery in Orsk has ceased all processing operations for an estimated six months following a Ukrainian drone strike on August 11, according to local governor Yevgeny Solntsev. The Orsknefteorgsintez refinery, located in Russia's Orenburg Oblast, suffered damage to critical infrastructure that cannot be immediately restored. Solntsev indicated that repairs will be lengthy due to the reliance on imported equipment and existing sanctions, potentially taking up to half a year.
The refinery, which has an annual crude-processing capacity of around 6 million tonnes, is over 1,300 kilometers from Ukraine. This attack is one of many recent long-range strikes by Ukraine targeting Russia's oil refining capabilities deep within its territory, a campaign that has escalated significantly in 2026.
Ukraine's ongoing strikes on oil depots and facilities aim to disrupt production and exacerbate domestic fuel supply issues within Russia, which have already led to export bans and price increases. Solntsev stated that local authorities are preparing for the worst-case scenario, which may necessitate reliance on imported fuel, though 80% of the region's 287 gas stations remain operational.
In related incidents, Ukrainian forces also targeted the Gazprom Neftekhim Salavat oil refinery complex in Russia's Republic of Bashkortostan overnight on August 13.
