The current development stage of engineering and technology for hydrocarbon production is characterized by a significant increase of production information on current status of gas and gas condensate fields technological processes. The task is to make a digital transformation the enterprises of the industry, where important part is take place the creation of automatically regulated intellectual fields and remotely controlled by groups of experts through situational centers. Intellectualization means that gas field has to go through the following stages: re-equipment existing control systems with the necessary instrumentation for remote monitoring and control of the gas and gas condensate production and treatment processes; digital twins development for calculating gas field operation multivariate scenarios; creating gas field distributed intellectual control system, which includes an automatic gas field control system (SAUP) and well control system (SAR). SAUP provides gas field optimal scenario calculation, selection and real-time control, while SAR provides keeping regimes set by SAUP and the safe operation of gas and gas condensate wells, including autonomous mode when communication with SAUP is lost. For SAUP real-time operation it is important to use artificial intelligence technologies along with physical and mathematical models of processes, which will accelerate predictive calculations and choose the optimal scenario for gas field. During digital transformation a three-level management system has to be implemented, including gas field level, a subsidiary level and a parent company level, each of them has its own characteristics. The concept of gas and gas condensate fields intellectualization, proposed by Rosneft employees, is based on modern ideas about necessary and effective digital transformation of production, which uses IT technologies, maximizes the potential of the reservoir and surface facilities. Gas fields equipped with intelligent control systems make possible to obtain additional hydrocarbon production, primarily due to the reduction of unproductive losses of reservoir energy arising from non-optimal “manual” regulation of wells and flows in the gas production and treatment system.
