Foreign and domestic experience in the use of technology to engage in the development of hard-to-recover reserves

The review of domestic and foreign experience of involvement in the development of hard-to-recover oil reserves using modern technologies is reviewed. In particular, physicochemical methods of action on the seam are distinguished: surfactants and ASP systems, thermal and thermal effects, the use of horizontal wells and multi-zone hydraulic fracturing of the formation. These methods are used in the development of oil fields in Western Siberia.
