The article highlights geological and physical features of the pre-Jurassic Triassic complex. Promising targets for prospecting and exploration of oil depositions have been outlined. Consistent patterns associated with reservoir type and dynamic parameters of wells have been identified. Mixed type wells (porous-fractured, porous and fractured) demonstrate a relatively stable production rate. Wells with predominantly fractured reservoir type demonstrate a rapid decline in production. Oil production from wells of the pre-Jurassic complex (the Triassic period) is performed using electrical submersible pumps (ESP). High formation temperature of 116°C, total salt content of about 50 g/l in the produced formation fluid, GOR over 120 m3/m3 are considered as complicating factors for the Triassic target operation. Decrease in the time between failures in the wells of the pre-Jurassic complex (the Triassic period) is caused by the formation of salt residues. Measures were taken to increase the mean time between failures of ESP units. The well stock has been divided into groups; salt hazard categories have been identified for each well group. Criteria for the use of additional ESP units at the salt hazardous well stock of the pre-Jurassic complex (the Triassic period) have been identified. The methodology for the use of an inhibitor for salt depositions has been developed to determine the priority of wells treatment. The saturation index has been defined taking into account the temperature increase in the pump to improve the efficiency of forecasting salt depositions formation in wells of the pre-Jurassic Triassic complex. The methodologies applied to the wells of the pre-Jurassic complex (the Triassic period) allowed to achieve the mean time between failures of 637 days and to increase the work efficiency at the salt hazardous well stock.
