Abstract
Results of numerical simulation of warm gas injection into a porous medium initially saturated with gas and gas hydrate, accompanied by gas hydrate dissociation, are presented. It is shown that depending on parameters at the outer boundary of the medium (permeable or impermeable to the gas flow) hydrate dissociation can occur both at the frontal boundary and in the extended region.
