ABSTRACT
This paper has reviewed the current state of development of oil fields with a low-permeable, clay-rich reservoir. Considered criteria for the applicability of the use of surfactants for enhanced oil recovery. On the basis of laboratory results, the effectiveness of using surfactants in the waterflooding system has been proved. According to the results of hydrodynamic modeling, additional oil production from the use of surfactants in the water-flooding system on a specific case was predicted. The results of the multivariate calculations of the injection of the surfactant solution are presented.
