Numerical modeling of the characteristic problems of dissociation of gas hydrates in a porous medium. One-dimensional formulation

In the paper some characteristic problems of dissociation of gas hydrates in a porous medium, which in the first approximation can be reduced to one-dimensional, are considered. These tasks include the study of the mutual influence of gas hydrates and climate, as well as important technological and ecological problems of the flow in the well or fault. Calculations using a mathematical model for the joint description of the gas hydrate zone and the zone with no gas hydrates are carried out. The calculation results showed the applicability of the developed methods to solving such problems.
