The paper analyzes the operation dynamics of injection and observation production wells. It assesses the impact of injection wells on produced water density. The reservoir is characterized by out-contour flooding. It was found that such a scheme is ineffective due to the weak hydrodynamic relationship of the reservoir with the aquifer, which is confirmed by the result of this analysis, and the selective (focal) water flooding used on the Kizelovsky horizon also does not have the proper effect, and there is no correlation of formation pressure with injection in observation wells. It was shown that large volumes of water injection into injection wells do not maintain formation pressure in certain areas, but in general, there is a slight positive impact on the development indicators for the target. The recommendations for optimizing the formation pressure maintenance system were proposed based on the results of the analysis.
