Annotation:

This paper presents the results of the study of a mathematical model describing the process of real gas filtration to a vertical well, taking into account the skin effect and the wellbore storage effect. A computational algorithm for estimation of reservoir filtration parameters based on the theory of inverse problems is proposed. The results of comparison of estimates of formation hydraulic conductivity, skin factor and formation pressure values obtained using the proposed algorithm and the analytical method are presented.
