A major oil refinery in Russia’s Tyumen region of Western Siberia has suspended crude oil processing and fuel production following a Ukrainian drone strike that damaged key refining units, according to two industry sources cited by Reuters.
Tyumen Governor Alexander Moor confirmed that a Ukrainian drone struck the refinery on Saturday, triggering a fire at the facility.
According to the sources, the July 25 attack damaged a diesel hydrotreater with an annual processing capacity of 2.6 million metric tons, as well as a combined high-octane gasoline production unit.
Industry officials said it is currently unclear how long repairs will take, leaving the timeline for resuming operations uncertain.
The refinery is owned by RI-Invest, which did not respond to Reuters’ request for comment.
The diesel hydrotreating unit had already been undergoing repairs following a separate fire on June 6 that was attributed to internal technical problems.
The Tyumen refinery has a total annual processing capacity of 9 million metric tons. In 2024, it processed 5.7 million metric tons of crude oil, producing approximately 500,000 metric tons of gasoline and 2.8 million metric tons of diesel, according to industry data.
The latest disruption adds to a series of Ukrainian long-range drone strikes targeting Russia’s energy infrastructure, a campaign aimed at disrupting fuel production and logistics supporting Moscow’s war effort.
