The main problem of exploitation of deposits with hard-to-recover reserves, including deposits of high-viscosity oil, is a low oil recovery factor (ORF) in the development of the basic impact - injection of the displacing agent and heat transfer agent. The review examines trends and prospects of physicochemical methods for enhanced oil recovery of heavy, high-viscosity oil fields developed on natural conditions and in combination with thermal methods. The main sources of current information are the materials of world congresses and annual international conferences on the problems of heavy oil production in countries that have significant geological reserves of heavy oils and bitumen. As one of the solutions to this problem, the creation and application of physicochemical methods of enhanced oil recovery based on nanoheterogeneous chemically evolved systems based on surfactants, both in the form of "cold" technologies and in conjunction with steam-thermal action on the formation are promising. The prospects for the concept of chemically evolving oil-displacing systems are confirmed by the results of field tests of technologies for enhanced oil recovery, created in the Institute of Petroleum Chemistry SB RAS.
