Abstract

The process of dissociation of gas hydrates coexisting with gas and ice in low-temperature reservoirs is considered. A qualitative analysis of the phase transitions which enables possible configurations of the solutions to be predicted is carried out on the basis of the phase diagram for methane hydrate. Mathematical models of hydrate decomposition in reservoirs which take into account the formation of an extended dissociation zone and the presence of two phase transition fronts are proposed.
