Due to the deterioration of the structure of oil reserves, the demand for enhanced oil recovery technologies is increasing every year. These technologies are usually classified into the following: Chemical, gas, thermal and combined enhance oil recovery methods. Among the chemical methods, polymer flooding stands out. It has been actively studied since the middle of the last century and currently numbers hundreds of completed projects around the world. Despite the relatively long study period and the number of publications dedicated to polymer flooding, there is still a range of aspects requiring research and development as well as field testing. One of the crucial issues at the preparation stage of a polymer flooding project is necessity to select oilfield or pilot area to achieve the best possible technological and economic efficiency results. This article provides analysis of the key factors influencing effectiveness of polymer flooding implementation. The paper reflects historical evolution, i.e. expansion of the technology applicability limits. Their current values have been verified, based on the analysis of the experience of implementing the technology in extreme conditions. Applicability criteria has been established as well for the polymer flooding development. The paper includes development of a uniquely designed integrated methodology for screening, assessment and ranking of promising objects for the technology implementation. The methodology is designed on the basis of a background review of completed projects, as well as on the expertise of the specialists involved in the development and scientific support of chemical enhanced oil recovery projects implementation. The purpose of the methodology is to create a basic universal tool for an express assessment of the prospects for using polymer flooding in different fields, which a wide range of specialists in the oil and gas industry could apply.
