Abstract: The study is dedicated to the technology of ASP-flooding (Alkali-Surfactant-Polymer-Flooding) the process of injecting into the reservoir a complex solution which includes surfactant, polymer and soda. The essence of technology is revealed in the research, the prospects of its application in the fields of Western Siberia are analyzed. The estimation of technological and economic efficiency of the method was carried out on the example of the Kholmogorsk oil field and the main reasons which hinder development of ASP-flooding at Russian objectsare identified. The calculation of technological efficiency is based on estimating the amount of additional oil production in the pilot area due to an increase of the oil displacement factorwith a change in the capillary number. For the mathematical modeling of ASP-technology, the differential equation describing the process of oil displacement from a selected volume of the formationwas used. The adsorption of the reagents was accounted for by Henry=s law. The estimation of profitability of the technology was made after its scaling to several similar areas of wells. Analysis of the structure of costs for the implementation of ASP-flooding showed that the main reasons for the loss of the project are high prices for imported reagents, specialized equipment and for its logistics. In order to find these problem solutions an analysis of foreign experience was made. The results of this research can be used to design ASP-flooding in Russian fields.
