At least half of production at Russian oil refinery halted after Ukrainian drone attacks

The work of at least half of the production of the Lukoil-Nizhnyohrodnaftorgsintez oil refinery in the city of Kstovo was stopped due to a drone attack. The reason was the failure of the AVT-6 crude oil processing plant, according to Reuters.
As previously reported, a drone attacked Lukoil-Nizhnyohrodnaftorgsintez, which is in the city of Kstovo, Nizhny Novgorod Oblast, on March 12.
Anonymous Russian sources in the industry told the newspaper that as a result of the attack, the main oil processing facility AVT-6 at Lukoil-Nizhnyohrodnaftorgsintez was damaged. According to them, this means stopping at least half of the production at the plant.
According to industry sources, Lukoil-Nizhnyohrodnaftorgsintez processed about 15.8 million tons of Russian oil per year, or 5.8% of the total volume of oil processed. The Defense Intelligence of the Ministry of Defense of Ukraine is behind this, according to sources in the Armed Forces of Ukraine. According to sources, the attack on the refinery in the city of Kstovo, the Nizhny Novgorod region, was organized by military intelligence.
Ukrainian drone attacks on Russian refineries are becoming more and more systematic. So, recently a drone attacked one of the largest oil refineries in Yaroslavl.
RBC-Ukraine's sources also reported that the Security Service of Ukraine drones hit the oil refinery in Tuapse, causing a massive fire.
In addition, Ukrainian drones successfully worked on the Ust-Luga Oil oil terminal. Fuel is processed there, which, in particular, is supplied to the Russian army.
Ukraine and Russia have often used drones to strike critical infrastructure, military installations and troop concentrations in their more than two-year war. Kyiv has concentrated fire on Russian refineries and energy facilities in recent months.
