Reserves of oil and gas in Russia

The Russian Federation published data regarding the oil and gas reserves of the country. According to this information, Russia possesses the reserves of about 29 billion tons of oil and 68 trillion cubic meters of natural gas. Certainly this information is only based on estimations; nobody can say how many reserves any of the countries indeed possesses. Although Russian officials suggest 30 years for the country to explore these reserves, this is also based on approximate assessment.
