Experience of enhanced oil recovery by CO2 injection in the U.S. fields

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.
