Application of enhanced oil recovery methods on Tatneft OAO fields

Historical development, current trends and future outlook for enhanced oil recovery (EOR) methods in Tatneft OAO determined by oil-field development issues is presented. The company proved to have a wide range of efficient, available and evolving, EOR techniques for various applications. The paper offers a special focus on application of EOR techniques for development of hard-to-recover reserves. A wide application of EOR methods to unconventional oil reserves development requires government motivation by means of lower mineral extraction tax rates. As for the company it should keep updating its EOR techniques.
