The CO2-in-Water (C/W) emulsion injection method is expected to be effective for gas recovery from low temperature hydrate reservoirs. We developed a two-dimensional numerical program to predict the flow behavior of C/W emulsion with hydrate formation in porous media and conducted numerical case studies of C/W injection in a two-dimensional system. Sensitivity analysis showed that there would be an optimal injection scheme for CO2 concentration and slug size to maximize the effect of gas recovery from the MH layer.
