Estimation of efficiency of the thermal method in the development of gas-hydrate deposits
Abstract In the work on the basis of the proposed mathematical model, the process of decomposition of methane hydrate under thermal action on the reservoir is numerically investigated. Based on the calculations, it was shown that the energy efficiency of the decomposition of methane hydrate, i.e. th...
