Kstovo refinery

The Kstovo refinery — formally operated as Lukoil-Nizhegorodnefteorgsintez — is one of Russia's largest petroleum refineries, located in the city of Kstovo in Nizhny Novgorod Oblast, approximately 400 km east of Moscow. It processes an estimated 17-18 million tonnes of crude oil per year, making it a significant node in Russia's mid-stream petroleum infrastructure. By May 2026, Reuters reported that Ukrainian drone strikes had halted or reduced operations at nearly all major central Russian refineries — including Kirishi, Ryazan, Yaroslavl, Syzran and Kstovo — cutting approximately 25% of Russia's total refining capacity, with gasoline output down 30% and diesel down 25%.

The facility is a critical supplier of refined petroleum products to Russia's military and civilian economy. Kstovo's Volga River location enables barge transport of both crude inputs and refined outputs, reducing dependence on pipeline flows from western Siberia. Lukoil, its parent company, has faced intensifying sanctions pressure since 2022, and the refinery's production disruptions compound the fiscal damage visible in Russia's Q1 2026 budget deficit figures.

Carnegie analyst Sergey Vakulenko has highlighted that cumulative strike damage across Russia's refining network forces operational adaptations — running damaged units at reduced throughput — that structurally compress margins and accelerate equipment degradation, with consequences that will persist well beyond any individual strike event.
