Oil reserves in Russia

In 2005, the Russian Ministry of Natural Resources estimated that another 4.7 billion barrels (0.75×10^9 m3) of oil exist in Eastern Siberia.

In October 2018, Russia's crude oil output grew to 11.61 million barrels per day (1.846×10^6 m3/d), a new post-Soviet record.

Significant reserves of unconventional tight oil such as contained in the Bazhenov Formation are believed to exist in western Siberia.

An estimate by Wood Mackenzie of the Bazhenov Formation was that it contained 2 trillion barrels of oil in place; achievable recovery factors are unknown.
