The target for analysis is the Vishnevo-Polyanskoye field exhibiting high reservoir micro-heterogeneity, as well as varying content of high molecular weight components in produced oils. In this context, it is necessary to select the most efficient methods to enhance oil recovery. For high-viscosity-oil fields, the best solution is to select those physical and chemical EOR methods that will provide both decrease of the interfacial tension and conformance control. Use of surfactants is an essential prerequisite for these technologies. Results of experimental studies have been analyzed concerning physical and chemical properties of salt and fresh water-based surfactant solutions.
