Modern trends in the development of domestic scientific thought in the field of hydrocarbon production are increasingly gravitating towards production management processes by regulating the operating modes of producing wells. At the current stage of development of production control technologies the tasks of process automation for managing well operating modes in the concept of using intelligent completion come to the fore, which is one of the main directions of field development in the context of a digital field. The intelligent completion system is used in single-lateral wells with simultaneous production from several intervals, in horizontal wells of extreme length, in multi-lateral/multi-branch wells to control production from each of boreholes. The unique advantages of the system include maximum growth in liquid hydrocarbon production, proactive development management, increased oil recovery and an overall reduction in the cost of well ownership. Highly accurate measurements of pressure, temperature, water cut and flow rates provide comprehensive reservoir management and are the basis for decision making.
