Rosneft Oil Company pays special attention to the application of a systematic approach to find the most effective methods of enhanced oil recovery (EOR). This article is devoted to the development of a procedure for the selection of deposits and fields favorable for gas EOR methods application in a large operating company with a large number of license areas A sufficient number of geological and physical criteria for the use of gas EOR methods are given in the world technical literature. However, as a more thorough study shows, they are mainly given for successful projects. Unsuccessful projects are often silenced or there is not any explication of low-performing. In addition, the range of reservoir properties during the actual testing of EOR methods is quite wide, and the factorial study of the influence of geological and physical conditions on the effectiveness of gas EOR is extremely low. The statistics of successful gas projects did not reveal strictly significant filtration properties affecting the efficiency of gas injection, but only indicates a wide range of applicability. The authors proposed a number of key geological and physical parameters that affect the efficiency of gas exposure processes. The main selection criterion is the technical and economic efficiency of the use carbon dioxide, hydrocarbon, flue gases and nitrogen for water alternated gas injection. The procedure is based on the results of the analysis of the world experience in the use of gas EOR projects, processing of accumulated experimental studies and numerical calculations on a sector composite model. It includes several steps: 1) the search for the threshold of the minimum required amount of oil and gas in the field based on the implementation of consolidated economic assessments; 2) the identification and consideration of geological, physical and technological stop-factors that hinder the effective use of gas methods; 3) ranking of the remaining deposits based on the introduced criterion of proximity of reservoir pressure to the minimum mixing pressure; 4) clarification of economic estimates of the use of gas EOR for the company's top-priority deposits; 5) identification and consideration of technological and infrastructural risks for ranking candidates. The approach proposed by the authors has been tested at the deposits and fields of Rosneft Oil Company and will be the basis for the formation of the company's long-term plans in the field of the use of gas EOR.
