Mathematical modeling of thermal impact on hydrate-saturated reservoir

The formulation problem of injecting a warm (with a temperature above the initial temperature of the reservoir) gas into a porous formation, which initially filled with methane and its hydrate, is given. A mathematical model of non-isothermal gas filtration is developed with allowance for the phase transition. An algorithm for solving this problem has been constructed, which makes it possible to calculate the main parameters of the thermal effect in the hydrate-saturated reservoir, accounting for dissociation of the gas hydrate.
