Rosneft Oil Company is No.1 in Russia in oil processing capacities and volumes.

The Company's Refining Block includes 13 major refineries operating in the Russian Federation: Komsomolsk Refinery, Angarsk Petrochemical Company, Achinsk Refinery, Tuapse Refinery, Kuibyshev Refinery, Novokuibyshevsk Refinery, Syzran Refinery, Saratov Refinery, Ryazan Refining Company, the refining complex of PAO ANK Bashneft (Bashneft-Novoil, Bashneft-Ufaneftekhim, Bashneft-UNPZ) and the Yaroslavl Refinery.

The Company's refining operations in recent years have been focused on meeting market demand for quality petroleum products.

Rosneft has been consistently implementing a program to modernize its refineries for a number of years, which has enabled it to expand the range and improve the quality of its products and increase their competitiveness. This is the most large-scale refinery modernization program in the Russian oil industry aimed at providing the market with high-quality motor fuels. As part of this program, since the end of 2015 the Company has been able to switch to 100% production of motor fuels of K5 ecological class for the domestic market of the Russian Federation in accordance with the requirements of Technical Regulation TR TS 013/2011.

Since 2018, a number of the Company's refineries have organized production of motor gasoline with improved environmental and operational properties: the Ufa Refinery, the Ryazan Transshipment Terminal and the Yaroslavl Refinery have launched commercial production of AI-100-K5 high-octane gasoline, while the Ryazan Refinery, Bashneft-Novoil, the Saratov and Syzran Refineries have launched production of AI-95-K5 Euro-6 gasoline.

Since 2019, the Komsomolsk, Achinsk, Syzran and Ufa refineries have been manufacturing low-sulphur marine fuel RMLS-40, which meets the requirements of the IMO international maritime organization introduced in early 2020. In 2019, the Company also started fueling ships with environmentally friendly TMC Type A fuel manufactured by the Novokuibyshevsk Refinery and Bashneft refineries.

In 2024, Rosneft continued to fully meet the growing needs of the domestic market for high-quality motor fuels.

The Company carries out systematic work to develop domestic technologies and import substitution and supplies its Russian refineries with its own catalysts required to manufacture motor fuels that meet modern standards.
