Key words: oil recovery factor (ORF), the methods of enhanced oil recovery (EOR), CO2 injection, additional oil production.
Various methods of enhanced oil recovery in the U.S. fields are considered. It is shown that injection of CO2 is the most common and effective method, since the largest amount of additional oil production is achieved owing to it. The data on the additional oil production in the U.S. due to a miscible and immiscible displacement at CO2 injection are given. The further increase of oil production by this method is forecasted.
