Ukraine's General Staff says two major Russian oil refineries stopped operating after Ukrainian strikes

Ukraine's General Staff announced on 4 September 2026 that two large Russian oil refining facilities — LUKOIL-Nizhegorodnefteorgsintez in Kstovo, Nizhny Novgorod Oblast, and the NOVATEK-Ust-Luga complex in Slobidka, Leningrad Oblast — have stopped operating after being hit by Ukrainian strikes. The LUKOIL plant was struck on 26 August, and the NOVATEK complex on 1 September, with damage to pipelines, processing units and hydrocracking columns reported at the latter.

Key points

  • Ukraine's General Staff confirmed on 4 September 2026 that two large Russian oil refineries have stopped operating after Ukrainian strikes.
  • LUKOIL-Nizhegorodnefteorgsintez in Kstovo, Nizhny Novgorod Oblast, was struck on 26 August 2026 and halted operations.
  • The NOVATEK-Ust-Luga complex in Slobidka, Leningrad Oblast, was struck on 1 September 2026, according to Ukraine's Main Intelligence Directorate (GUR).
  • At the NOVATEK-Ust-Luga complex, pipelines between the oil delivery pump station and reservoirs were damaged, and a pipeline fire in the reservoir group caused an oil spill of about 250 square meters.
  • The primary gas condensate processing unit and two hydrocracking unit columns were hit at the NOVATEK-Ust-Luga complex.
  • The LUKOIL plant has a reported capacity of approximately 17 million tons of oil per year and produces gasoline, diesel, aviation fuel, and lubricants.
  • Reuters, citing informed sources, described LUKOIL-Nizhegorodnefteorgsintez as Russia's fourth-largest refinery and second-largest gasoline producer, and reported that resumption timelines were unknown.

Why it matters

The stoppages remove capacity at two large Russian refining facilities that, according to the Ukrainian General Staff, supply the needs of the Russian armed forces. Reuters, citing informed sources, reported that the LUKOIL plant is Russia's fourth-largest refinery and second-largest gasoline producer, and that, as of its reporting, all main LUKOIL refineries in Russia were not operating, with no known restart timelines — pointing to a sustained impact on Russia's domestic fuel output beyond a single incident.

What happened

Ukraine's General Staff stated on 4 September 2026 that two major Russian oil refining enterprises have stopped operating after being struck by Ukrainian forces. The first, LUKOIL-Nizhegorodnefteorgsintez in Kstovo, Nizhny Novgorod Oblast, was hit on 26 August 2026 and was confirmed offline after additional data analysis. Reuters, citing informed sources, reported the stoppage following that attack. The facility has a capacity of about 17 million tons of oil per year and produces gasoline, diesel and aviation fuel, lubricants, and other petroleum products.

The second, the NOVATEK-Ust-Luga complex in Slobidka, Leningrad Oblast, was struck on 1 September 2026 by Ukrainian drones, according to Ukraine's Main Intelligence Directorate (GUR). At that site, pipelines between the oil delivery pump station and the reservoirs were damaged, and the primary gas condensate processing unit and two columns of the hydrocracking unit were hit. A pipeline fire in the reservoir group was accompanied by an oil spill of about 250 square meters.

The General Staff said both enterprises are involved in supplying the needs of the Russian armed forces. Reuters reported that exact timelines for resuming work at the affected LUKOIL refineries were unknown at the time of reporting.

How Ukrainian sources describe it

Ukrainian sources place the General Staff of the Armed Forces of Ukraine and Ukraine's Main Intelligence Directorate (GUR) at the center of the story, presenting them as the authoritative voice confirming the stoppages and the military significance of the targets. Coverage names LUKOIL and NOVATEK directly, details the damage to specific equipment — pipelines, hydrocracking columns, the primary gas condensate processing unit, and oil spill areas — and frames both facilities as suppliers to the Russian armed forces. All sources in this cluster are Ukrainian.

How international sources describe it

International framing in the available reporting is limited to Reuters, which adds market-scale context: it characterizes LUKOIL-Nizhegorodnefteorgsintez as Russia's fourth-largest refinery and second-largest gasoline producer, and notes that, as of its reporting, all main LUKOIL refineries in Russia were not operating, with restart timelines unknown. Reuters' reporting foregrounds industry impact and uncertainty about resumption rather than the Ukrainian-military attribution that dominates the Ukrainian sources.

Background

The LUKOIL-Nizhegorodnefteorgsintez refinery in Kstovo was struck on 26 August 2026; the NOVATEK-Ust-Luga complex in Slobidka, Leningrad Oblast, was struck on 1 September 2026. Reuters cited informed sources reporting the LUKOIL stoppage after the 26 August attack, with exact resumption timelines unknown at the time of reporting. Ukraine's Main Intelligence Directorate (GUR) reported that the NOVATEK-Ust-Luga complex was hit by Ukrainian drones on 1 September.
