Strike on TANECO’s largest crude unit threatens major share of refinery’s processing capacity

Ukrainian FP‑1 drones hit the TANECO refinery’s ELOU‑AVT‑7 unit in Nizhnekamsk on 13 September, targeting the plant’s largest primary oil‑processing line with a capacity of 9.2 million tons a year. Analysis cited by Ukrainian observers suggests taking this unit offline could remove about 52% of the refinery’s primary processing capacity.

Ukraine’s long‑range drone campaign against Russian energy infrastructure has reached one of the country’s key refineries.

On 13 September, Ukrainian forces struck the TANECO oil refinery in Nizhnekamsk using FP‑1 drones. According to available reporting, the attack hit the ELOU‑AVT‑7 unit, which is described as the refinery’s largest primary oil‑processing facility.

The ELOU‑AVT‑7 unit has an annual capacity of 9.2 million tons of crude. An analysis by DniproOsint estimates that if this unit is taken offline, around 52% of TANECO’s total primary oil‑processing capacity would be halted. In other words, just over half of the crude that would normally be handled by the plant’s main distillation units could be affected while repairs or rerouting are arranged.

Primary units like ELOU‑AVT‑7 perform the initial separation of crude oil into different fractions that feed the rest of a refinery. When such a unit is disrupted, secondary units that produce gasoline, diesel, jet fuel and other products may have to idle or run below capacity.

The strike fits with Ukraine’s broader use of relatively low‑cost drones to hit high‑value energy targets far from the frontline. Reaching a unit of this size at TANECO underscores that refineries deep inside Russia remain within the range of Ukrainian systems.

There is no detailed public information yet on the extent of physical damage to ELOU‑AVT‑7, the duration of any outage, casualties or environmental impact. The scale and length of disruption will depend on how quickly Russian operators can repair equipment and whether they can redistribute crude to other units or refineries.

For Russia, any prolonged loss of primary processing capacity at TANECO would complicate fuel supplies and refinery planning, even if national‑level output can be smoothed by shifting flows elsewhere.

Key indicators to watch now include commercial or satellite imagery showing damage and repair work at the refinery, Russian announcements about operational status at TANECO, and whether Ukraine targets similar primary units at other large refineries, which would point to a sustained campaign against Russia’s oil‑processing backbone.
