dc.description.abstractA simulation study on the effects of capillary pressure on methane gas recovery from methane hydrates was conducted using STOMP-HYD. Four stimulation recovery methods were examined in the study; thermal stimulation, depressurization above the Q-point, depressurization below the Q-point, and CO₂ micro-emulsion injection. Van Genuchten parameters pertaining to moisture retention characteristics for soil types ranging from coarse to fine grained were introduced into the simulations to quantify what role capillary force plays in methane gas recovery. It was observed that greater capillary forces resulted in gas production occurring sooner in all four stimulation cases. It was found that greater aqueous saturations resulted due to the higher capillary forces. The greater aqueous saturation allow for greater heat transfer through the porous media. As a result of greater heat transfer, CH₄ hydrates dissociate sooner in the cases where high capillary forces were observed, lending to faster production rates.en_US
