Antipinsky refinery

The Antipinsky refinery (Russian: Антипинский НПЗ, romanized: Antipinskiy NPZ, IPA: [əntʲipʲinʲskʲi]), colloquially known as the Tyumen Oil Refinery, is a Russian oil refinery located in south-east Tyumen, Tyumen Oblast, adjacent to the Tyumen trunk oil pipelines and the Tyumen-3 pumping station. It is one of the largest refineries in Russia, participating in the Urals and West Siberian oil market, where it is the only refinery in operation in the Ural Federal District. As of 2025, it is Russia's largest privately owned oil processing plant, with a total processing capacity of nine million tons of crude oil per year. It is also the only oil refinery constructed in Russia since the dissolution of the Soviet Union. Antipinsky has grown rapidly since it first began operation, with an almost nine-fold increase in production rates since the plant's inception in 2006. However, this expansion was largely as a result of debt from both Russian and European lenders, and by the late 2010s, the refinery was financially dependent on regular borrowing and prepayments from customers. The owner of the refinery was declared bankrupt in 2019, and both the chief executive officer and majority shareholder, Dmitry Mazurov, were arrested for fraud. The refinery ceased operations for three months following the arrests, before production resumed under new ownership. Mazurov was later jailed for ten years in a high-security penal colony for his role in the fraud and embezzlement, despite prosecutors requesting a sentence of 16.5 years.
