Abstract
A homogenized model of non-isothermal compressible two-phase flow accompanied by dissociation of a gas hydrate in a fractured porous medium is derived. The equations of the homogenized model contain non-local in time source terms corresponding to the contribution of the gas hydrate in the matrix blocks. The model of phase behavior of a gas hydrate is used that admits coexistence of the hydrate and products of its decomposition in a finite region of the phase diagram. This possible behavior is a consequence of non-linearity of the skeleton potential dependence on the depth of phase transition.
