Bottomhole pressure of wells is one of the key parameters determining the efficiency of production wells operation and development of oil and gas fields. In this paper, based on statistical data and the results of field studies, the issue of substantiating the optimal bottom-hole pressure of producing wells is considered. The analyzed sample is represented by 80 producing wells, and more than 55 % of wells are operated at bottom-hole pressure above saturation pressure. As part of the study, the indicator diagrams of producing wells at bottomhole pressure below the saturation pressure were analyzed using the method of steady-state sampling. According to field research data, indicator diagrams are given for different water content of reservoir products and methodological recommendations are given for determining the effective pumping mode, in which the maximum flow rate of the well is achieved for liquid and oil at bottom-hole pressure below saturation pressure.
