INCREASING OIL WELL SERVICE ECONOMIC EFFICIENCY
The aim of the study is to develop an algorithm for the maintenance of oil wells, which helps to maintain the target level of oil production and improve the efficiency of oil production enterprises. The methodological basis of the research was an analytical study of theoretical scientific literature, a systematic approach, analysis and synthesis, identification of cause-and-effect relationships. The study identifies measures for carrying out service work on oil wells in order to optimally allocate investments, and proposes criteria for selecting a well when carrying out service work in a petrochemical complex, which ensures their efficiency. A model for choosing the order of work on well workover is proposed, which implies the allocation of four zones in the matrix field, which characterize the cumulative effect of priority indicators for selecting a well for service work. In order to manage projects for the formation of costs for carrying out service work, an algorithm has been developed for selecting wells for their inclusion in the workover program, taking into account budgetary constraints, which will allow assessing the economic efficiency of each well separately and conducting a comparative analysis. Practical application of the approach to assessing the feasibility of service work for each well, based on an individual assessment, will increase the reliability of the economic justification for workover programs for oil companies.
