Key words: oil recovery, oil recovery ratio, the methods of enhanced oil recovery, bottomhole zone treatment, the additional production due to methods of enhanced oil recovery and bottomhole zone treatment.
The problems of reserves estimation and the oil recovery ratio determination are considered. It is shown that the oil recovery conceptions depend on the reliability of information on the geological structure of the specific object and applied headway technologies. It is noted that an effective application of the methods of enhanced oil recovery in the fields with hard-to-recover reserves plays the principal role in problems of the innovative design, the organization of works on the creation, testing and implementation of methods of enhanced oil recovery has no less importance. The basic ways to stimulate methods of enhanced oil recovery implementation and improve the final oil recovery ratio are suggested.
