Ukraine drone strike halts oil processing at Tyumen refinery
A Ukrainian drone attack on the Tyumen oil refinery in western Siberia has completely halted crude oil processing and petroleum product output after damaging secondary processing units.

Drone strike and subsequent fire
On Saturday, July 25, a Ukrainian drone struck the Tyumen refinery in the Tyumen region, triggering a fire at the facility. According to industry sources, the drone strike ignited a diesel hydrotreating unit with an annual capacity of 2.6 million metric tons, as well as a combined high-octane gasoline production unit. The sources noted that it is difficult to estimate how long repairs will take.
Production halt
As a result, the refinery fully stopped processing crude oil and producing petroleum products. The refinery has a total production capacity of 9 million metric tons per year. In 2024, it processed 5.7 million metric tons of crude oil, yielding 0.5 million metric tons of gasoline and 2.8 million metric tons of diesel, according to the sources.
Previous repairs
The diesel hydrotreating unit was already undergoing repairs following a fire on June 6 caused by internal technical issues. The timeline for restoring the damaged equipment remains unclear.
Owner's response
RI-Invest, the owner of the Tyumen refinery, did not respond to a Reuters request for comment.
