The paper reviews forecasting of main development parameters, as well as pressure and gas-condensate saturation distribution in each formation, general gas offtake from the deposit and each layer separately. Herewith, for consideration of all development process aspects, the systems of equation describing filtration process of gas-condensate mixture, phase state equation and the one of differential depletion with their initial and boundary conditions were jointly solved. It provides consideration of physical parameters change in gas-condensate mixture in development mode depending on the pressure and temperature for any phase of joint formation exploitation, which enables predicting technological indexes of development process.
