A distinctive feature of the fields of Western Siberia located in the late stage of development is the high water content of the products. The technological policy of the subsoil user is to apply relatively “not costly” methods to limit water inflows. Allowing, without additional economic costs, to reduce water cut, leading to an increase in oil production. This list includes: flow diverting technologies, including alignment of the injectivity profile of injection wells; repair and insulation works in production wells, hydrodynamic methods, in particular forced fluid withdrawal, cyclic flooding. In this paper, we consider the technology of the use of flow diverting reagents that can increase the volume of hard-to-recover reserves not involved in the development. The analysis of the efficiency of injection of gelling compositions into injection wells is carried out. The calculation of additional oil production from the use of flow diverting technologies is carried out. The estimation of the duration of the effect of applying this technology is calculated.
