The peculiarities of the gas hydrate decomposition to gas and ice during the gas extraction from the porous medium initially saturated with methane and its hydrate are studied. It is shown that at a negative initial reservoir temperature, the gas hydrate decomposition always occurs with the formation of ice either on the frontal surface or in the extended region. It is established that the extended region of hydrate dissociation is characteristic for large values of the mass flow rate of the gas extraction.
