Abstract: The phase permeability hysteresis and layer absolute permeability heterogeneity of aquifer reservoir affects are studied when gas injection and production cycles simulate an underground gas storage operation. Basic data of the numerical model correspond to the parameters of real UGS objects existing in Russia. The results of calculations for different versions of basic data showed that the observed heterogeneities lead to the deformation of the geometrical form gas saturated field and phase permeability hysteresis affects the gas saturation distribution over the gas field volume
