Russia's largest oil company, "Rosneft", is facing rising restoration costs for its oil refineries after Ukrainian attacks. The company fears that even a continuation of the war for a few more months could cause long-term damage to its business.

On October 22, Bloomberg reported this, citing informed sources and internal damage assessments of the facilities.

According to the agency's interlocutors, the costs of constant refinery repairs are becoming unsustainable in the long term. Some plants are deliberately stretching out equipment restoration: work that usually takes a few days can now take weeks. The reason is repeated drone strikes, including on facilities that have just been repaired.

Western sanctions have become an additional problem. Russian enterprises find it harder to obtain spare parts for technological equipment that was previously supplied by European and American manufacturers. Russian and Chinese analogues sometimes have to be waited for months for, and they are not always compatible with existing installations.

Among the most affected enterprises are the Ryazan, Syzran and Tuapse refineries. According to Bloomberg estimates, the Ryazan plant has been idle for more than half the time since May, the Syzran plant has not worked or used less than a third of its capacity for most of the last six months, and the Tuapse refinery has remained shut down since April.

The problems are also affecting the company's financial performance. In the first half of 2026, the volume of oil refining at Rosneft's enterprises decreased by about 8%, and net profit decreased by 18.4%. At the same time, financial results are also influenced by other factors, not just plant damage.

According to Bloomberg, company management is increasingly concerned that repeated attacks, prolonged production shutdowns, and repair difficulties could lead to accumulated losses, the consequences of which would be felt even after the cessation of hostilities.
