Abstract
A mathematical model of vertical interference testing of a gas reservoir penetrated by an imperfect vertical well is considered. The effect of the vertical and horizontal permeability and the degree of reservoir penetration on the pressure variation curves in the active and responding well intervals is investigated. A method for interpreting the results of vertical interference testing of a gas reservoir based the theory of inverse problems is proposed. It is shown that the results of vertical interference testing of a gas well can be used to estimate the vertical and horizontal permeability and porosity of the reservoir in the case of its full penetration.
