Ukrainian Drones Strike Russian Oil Refinery in Samara Region: Fatalities and Injuries Reported

Attack on the Novokuybyshevsk Refinery

According to Главком: Ukraine’s defense forces have struck the Novokuybyshevsk oil refinery located in Russia’s Samara region. The drone assault continued for a second consecutive night, and according to local authorities, one person was killed and two others were injured as a result. Governor Vyacheslav Fedorishchev confirmed the death of a resident during the attack in Novokuybyshevsk, where windows were blown out in one apartment building. Residents of both Samara and Novokuybyshevsk also reported explosions during the strikes.

Threat to Civil Aviation

The refinery attack also posed a risk to civilian air travel-the Kurumoch Airport in Samara temporarily halted its operations. Notably, the Novokuybyshevsk refinery processed 5.74 million tons of crude oil in 2024 and produced:

• 1.10 million tons of gasoline;
• 1.64 million tons of diesel fuel;
• 1.27 million tons of fuel oil.

Earlier, drone strikes had already forced the suspension of operations at both the Tuapse and Novokuybyshevsk refineries, which are part of Rosneft.

Additionally, the attacks also hit the Gorky oil pumping station in the Nizhny Novgorod region. This station is part of the Transneft – Upper Volga network and is responsible for pumping oil toward Belarus, Europe, or onward to other nodes and refineries. It is worth recalling that on April 18, the Samara region was subjected to a massive drone assault, with the main impact concentrated on the city of Novokuybyshevsk.

In April, Russia’s oil industry experienced its sharpest decline since the Covid-19 pandemic. Crude production in the country fell by hundreds of thousands of barrels per day due to infrastructure damage. Reuters analysts noted that Russia cut oil output and limited supplies to Europe as a result of Ukrainian drone attacks. According to expert estimates, by April 2026, Russia’s production volumes could drop by 300,000 to 400,000 barrels per day, potentially marking the steepest monthly decline in six years.

These strikes on strategic Russian oil infrastructure highlight the ongoing conflict between Ukraine and Russia amid escalating hostilities.

The reduction in Russia’s oil output could carry serious economic consequences, including impacts on international supplies and energy prices. The situation remains tense, and further actions by both sides may significantly influence the course of the conflict and the region’s economic stability.

The recent drone strikes on the Novokuybyshevsk refinery are part of a broader strategy targeting critical oil infrastructure in Russia. This offensive not only disrupts local operations but also poses significant challenges to Russia's overall oil export capabilities.
