The PDF file of this paper is in Russian. 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.

Abstract A case study of a gas-condensate field located on the northeastern shelf of Sakhalin Island demonstrates the possibility of development of condensate-containing gas reserves by drilling very long ERD wells (drilling from the shore). The development system described in the paper includes drilling well with upward orientation. Such design provides complete cleaning of a wellbore from fluids and solids accumulated over a long period of maintenance-free operation. The choice of a development system using horizontal wells is also associated with the geological structure of the field (massive type accumulation with a single gas-bearing contour is broken by tectonic faults into separate blocks with different hypsometric elevations). Under the technical, economical (drilling from platform and from land, the use of subsea production systems, ice gouging with hummocks), and environmental (presence of valuable fish species in water areas and permanent residence of indigenous peoples) limitations, the development of individual wells with vertical completions turned out to be unprofitable. For the first time for this type of accumulation located in a coastal zone, a unique method of monitoring the recovery of reserves within the cross-section, as well as movement of the gas-water contact without the use of monitoring and pressure observation wells was suggested.

Abstract The paper investigates the processes of condensate recovery from low-permeable formations during depletion-driven development of gas-condensate deposits. The studies were based on simulating multi-component flow of various gas-condensate mixtures in reservoirs with a large range of permeabilities. As a result, the key causes of decreased condensate recovery from low-permeable formations compared to "regular" reservoirs have been established. It was shown that for low-permeable formations, due to large pressure drawdown cones, the additional condensation of C5+ components because of an "non equilibrium" effect is possible, where the flowing gas phase is out of equilibrium to the retrograde condensate. The main technological factors influencing the condensate recovery from low-permeable formations were identified, as well as possible ways to increase condensate recovery.
