hydrate in porous media using depressurization, two-cycle warm-water injection and a combination of the two methods were … using the three methods. The driving force of the hydrate dissociation at different stages of depressurization was analyzed … advantages for hydrate exploitation over the depressurization and warm-water-injection method in terms of the energy efficiency …

a single vertical well by depressurization. The simulation results indicated that for a 1.5 MPa wellbore pressure, the … total gas hydrates in the simulated system. The results may suggest that the single vertical well by depressurization method …, such as a horizontal well design or the combination of depressurization and thermal stimulation, may be more economically …
