The article describes the criteria for the introduction of gas-stabilizing devices in the wells of high-temperature layers of the Krasnoleninsky arch deposits. A method for calculating the gas content at the pump intake is presented. The current structure of the production fund of wells is determined by the presence of gas content at the receiving pump of the pre-Jurassic layers of the Krasnoleninsky arch deposits, according to the above method. 54% of the production fund of wells with ESP is operated with gas pumping at the pump reception of more than 50%. The dynamics of changes in gas retention at wells launched after geological and technical measures during the year are described. The choice of gas-stabilizing devices for the operation of wells in pre-Jurassic formations with ESP should be carried out depending on the accompanying complicating factors. Taking into account the complicating factors in the operation of wells in the pre-Jurassic reservoir of the Krasnoleninsky arch deposits, the complete set of additional equipment for the electric center pump is determined. Based on the Oddo – Thomson method adapted to the conditions of high-temperature reservoirs developed and implemented in the production of salt hazard criteria. Salt hazard criteria include three groups that describe the location of the salt formation process during the operation of ESP installations. For salt hazard categories, the criteria for the introduction of additional equipment in the operation of electric center-mounted pumps are defined. Targeted use of expensive additional equipment allowed to increase the efficiency of its use. The effectiveness of the introduction of additional equipment has affected the growth of the development of the complicated fund of wells in the pre-Jurassic formations.
