Abstract: This paper presents a mathematical model for the methane hydrate-carbon dioxide replacement by injection of carbon dioxide into a porous medium rich in methane and its gas hydrates. Numerical solutions describing the pressure and temperature variations in a reservoir of finite length are obtained. It is shown that the replacement process is accompanied by reducing the pressure and increasing the temperature of the porous medium. It is established that during the time of complete replacement of methane from a reservoir decreases with increasing permeability of the porous medium and the pressure of the injected gas.

Keywords: porous medium, gas hydrate, filtration.
