Russia's Ryazan oil refinery halted a processing unit after a drone attack, affecting fuel supply. The attack is part of Ukraine's strategy against Russian infrastructure.
(Reuters) -Russia's fourth-largest oil refinery, the Ryazan plant located south east of Moscow, halted a primary crude distillation unit on Wednesday following a Ukrainian drone attack, two industry sources told Reuters on Friday.
Ukraine has stepped up its attacks on Russia's energy infrastructure as peace talks mediated by U.S. President Donald Trump have not progressed.
Such attacks have been behind motor fuel shortages across several regions in Russia, local authorities have said.
Ukraine's general staff said on Thursday that Kyiv's forces had struck the Ryazan oil refinery.
The industry sources in Russia told Reuters the CDU-4 processing unit, was urgently halted on Thursday after it caught fire following a drone attack.
The unit's capacity stands at 4 million metric tons a year, or 80,000 barrels per day, accounting for around a quarter of plant's total capacity.
Oil company Rosneft, which owns the refinery, did not respond to a request for comment. The sources said the plant is still processing oil, but at a reduced volume.
One of the sources said some adjacent units were also halted, including a reformer, vacuum gasoil hydrotreater and catalytic cracker.
The refinery processed 13.1 million tons of crude in 2024, producing 2.3 million tons of gasoline, 3.4 million tons of diesel and 4.2 million tons of fuel oil.

A crude distillation unit (CDU) is a facility used in oil refineries to separate crude oil into various components based on their boiling points. It is a critical part of the refining process.
A drone attack refers to the use of unmanned aerial vehicles (UAVs) to strike a target. In the context of military operations, it often involves targeting infrastructure or military assets.
Motor fuel is a type of fuel used to power vehicles, including gasoline and diesel. It is derived from crude oil and is essential for transportation.
An oil refinery is an industrial facility that processes crude oil into usable products such as gasoline, diesel, and other petrochemicals. Refineries play a crucial role in the energy sector.
Energy infrastructure includes the facilities and systems that generate, transmit, and distribute energy. This encompasses power plants, refineries, pipelines, and electrical grids.
