The article considers and solves the problem of finding the optimal strategy for the development of terrigenous deposits of the Bobrikovsko-Radaev horizon of one of the deposits of the Ural-Volga region. Based on the analysis of the behavior of the curves obtained during geophysical surveys in more than three thousand wells, four main types of facies zones were identified, characterized by different porosity and permeability properties and formed development systems. As part of the analysis of the reservoir pressure maintenance system, a direct influence of reservoir properties on the efficiency of waterflooding was established, which made it possible to develop an optimization strategy and the formation of new injection sites. Using the method of multiple regression analysis, two statistical models have been obtained – the reservoir properties model and the facies model, which make it possible to quickly assess the recovery factor and select the optimal development system for fields with a lesser degree of knowledge.
