In the presented work, a comprehensive analysis of geological and commercial data on three low-yielding deposits associated with the East Orenburg arch was carried out. Based on the use of the methodology for calculating statistical values of the truncated normal distribution, a formula is proposed adapted for unproductive facilities, the drainage of which is carried out using special technologies and equipment (short-term periodic operation mode) and (or) in a classical way with an unstable supply coefficient of deep-pumping equipment. Based on the comparison of the obtained intermediate and main research results, the regularities of geological, technological and operational characters have been established, which significantly improve the efficiency of planning and conducting various geological and technical measures. The general trend of similarity in quantitative and qualitative ratio is highlighted, which allows us to use this to solve specific problems of effective development of low-productive deposits of carbonate reservoirs. Keywords: mechanized well stock; geological and statistical models; mathematical modeling; deep pumping equipment; oil recovery coefficient; hydrodynamics of reservoir processes.
