Hydrate Formation Characteristics during Carbon Dioxide Flow Through Depleted Methane Hydrate Deposits
Abstract Depleted methane hydrate (MH) reservoirs are potential sites for CO 2 storage. Hydrate formation during the CO 2 flow process in a dissociated MH sample was simulated to clarify the formation characteristics of CO 2 hydrates and their effect on CO 2 storage. Experiments included MH formatio...
