Abstract:

The Markovskoye field is a large hydrocarbon reservoir located in the North Caucasus region of Russia. The paper analyzes the physicochemical properties of the produced gas and calculates the possibility of its underground storage using the MathCad software package. The main objectives of the study include determining the characteristic boiling points of oil and gas condensate fractions, calculating the density, molecular weight, saturated vapor pressure, critical parameters and reduced constants, compressibility coefficient, fugacity, viscosity, thermal properties, as well as analyzing the mass, volume and molar composition of the gas. In addition, the elastic gas reserve in the reservoir was calculated, the dynamics of gas extraction and changes in reservoir pressure in the constant depression mode on the reservoir were calculated.

Keywords: pressure., critical temperature, volumetric composition, Density, Compressibility, Fugacity, Fraction, gas
