Surgut Oil and Gas Corporation (SNG) is one of the three largest Russian oil companies with more than 86,000 employees and is the 11th largest oil company in the world. Since the first discovery of oil fields in western Siberia in 1961, the total oil production in the SNG field has exceeded one billion tons. Today, SNG's oil production accounts for one-eighth of Russia's total oil production, and natural gas production accounts for one-third of total domestic production. SNG also undertakes a quarter of Russia's oil exploration and mining tasks, and oil production is growing steadily year by year. It has made positive contributions to the Russian industry, national defense, railway, aviation and people's lives.
