The Kstovo oil refinery: what is known?
The Kstovo oil refinery (Lukoil-Nizhegorodnaftorgsintez LLC, also known as NORSI) is one of Russia’s largest oil refineries and a key facility for Lukoil. It is located approximately 15 km from Nizhny Novgorod.
- commissioned in 1958;
- it is one of Russia’s four largest oil refineries;
- has a refining capacity of around 16–17 million tonnes of crude oil per year (approximately 320,000 barrels per day);
- is one of the largest producers of petrol, diesel fuel, jet fuel, bitumen and lubricants in the Russian Federation.
The plant produces fuel, some of which is used to meet the needs of the Russian army and for military logistics. As a result, the plant has repeatedly been targeted by Ukrainian drones.
