Description
Summary:In plane-parallel approximation, a computational study of a thermal effect on a reservoir, pores of which in the initial state are filled with carbon dioxide hydrate, was carried out. Top and bottom reservoir boundaries are impermeable to the products of gas hydrate decomposition, the bottom boundary temperature Te is higher than the initial reservoir temperature T0. It was shown that, with a relatively small difference between Te and T0, the decomposition of CO2 hydrate occurs only in a small area adjacent to the bottom reservoir boundary, i.e. underground gas hydrate storage of carbon dioxide is a reliable way to utilize it.
