Numerical research of the gas extraction methods from a deposit saturated with methane its hydrate

In plane-parallel approximation the mathematical formulation of the problem of gas extraction from a deposit saturated with methane and its hydrate is given. The cases of depressurization and thermal effects on the deposit are considered. For these cases of gas extraction the calculations results of the cumulative gas production and the amount of decomposed gas hydrate for various values of the initial reservoir hydrate saturation are presented and discussed.
