In a one-dimensional linear formulation, the problem of methane production from a deposit initially saturated with methane and its hydrate is considered. Three cases were considered, namely: methane production only due to pressure reduction at one reservoir boundary; pressure reduction at one reservoir boundary and heating from the opposite boundary; pressure reduction at one reservoir boundary and carbon dioxide injection at the opposite boundary (replacement method). A numerical study has shown that the most effective is a combination of the depression and replacement methods. With this combination the largest amount of methane is extracted in a shorter period, and a large amount of carbon dioxide is buried.
