The production of energy resources in Russia is profitable both economically and in terms of energy production. Currently, Russian oil and gas companies have a policy of increasing energy efficiency, which will led to an increase in the energy return on investment (EROI) of both oil and gas production as a whole, and of separate companies in particular. By our calculations, the EROI for oil production in Russia differs for the different companies, and in 2012 was in the range of 22–35:1. The EROI for light oil products in 2012 was in the range of 5–13:1. Keywords: EROI; oil production; Russia 1. Introduction Over the last 110 years, the annual consumption of energy resources in the world has increased 20 times from 0.6 in 1900 to 12.4 billion tons of oil equivalent (toe) in 2012 [1,2].
