Fire Breaks Out After Attack on Russia's Fourth Largest Oil Refinery
The LUKOIL NORSI refinery in Kstovo, Nizhny Novgorod Oblast, Russia, was reportedly attacked by drones overnight from August 25 to 26, with videos showing a large fire erupting near the facility. Local authorities have not yet issued a formal statement regarding the attack's target, damaged equipment, or production stoppage.
Multiple independent monitoring channels and local residents reported several explosions around midnight in Kstovo, followed by a significant fire; existing footage confirms the fire, but it is not possible to verify the drone strike's impact location, burning units, and actual damage based solely on public videos.
The targeted facility is LUKOIL-Nizhegorodnefteorgsintez, also known as NORSI, with a designed crude oil processing capacity of approximately 17 million tons per year, making it one of Russia's fourth largest refineries and a major gasoline production base.
The refinery produces gasoline, diesel, aviation fuel, lubricants, asphalt, and other petrochemical products, providing fuel for Russia's domestic economy and military logistics. The claim that "the refinery's gasoline accounts for 11% of the national total" has not been reliably verified in this English report; a more cautious statement is that it is one of Russia's second largest gasoline production facilities.
Kstovo is located about 800 kilometers from the Ukrainian border. Reports indicate that the refinery has been targeted by drone attacks multiple times in 2026, including on April 5, May 20, June 24, and July 2; repeated strikes mean that risks depend not only on a single fire but also on whether repairs, spare parts, and air defense resources can keep pace.
As of now, Ukraine has not publicly claimed responsibility for this attack, and Russian officials have not disclosed capacity losses, casualties, or firefighting progress. Therefore, the terms "attacked and caught fire" cannot be directly equated with the complete withdrawal of the 17 million tons annual capacity or a nationwide fuel supply interruption in Russia.
In market terms, if the fire affects key units such as vacuum distillation, catalytic cracking, hydrogenation, or blending, the domestic supply of gasoline, diesel, and aviation fuel in Russia will rely more on inventory allocations, increased production from other refineries, and regional logistics alternatives; crude oil may be forced to shift to exports or other processing plants. Beneficiaries are typically refineries and finished oil traders that can provide alternatives, while those under pressure include regional retail fuel, military and civilian logistics, and downstream customers reliant on the refinery's supply chain; the actual price impact depends on the production stoppage period and alternative capacity.
