Gazprom Neft is one of Russia’s largest and fastest-growing oil and gas producers. The key areas of the company’s operations include the exploration, development, production and sale of oil and gas, as well as oil refining and the marketing of petroleum products. Gazprom Neft operates in the largest oil and gas regions in Russia, such as Khanty-Mansiisk Autonomous District, Yamal-Nenetsk Autonomous District, and Tomsk and Omsk Regions. The company’s major oil refineries are located in Omsk, Moscow and Yaroslavl Regions (the last co-owned by TNK-BP via the joint Slavneft subsidiary). Through its consolidated refineries in Omsk and Moscow Regions, the company can refine almost all of the crude that it produces, demonstrating one of the best production-to-refining ratios in the industry. Gazprom Neft is one of Russia’s top five companies in terms of crude production, refining and sales of petroleum products.
