Experimental study on gas production from methane hydrate in porous media by huff and puff method in Pilot-Scale Hydrate Simulator

► We develop a novel three-dimensional 117.8-L cubic pressure vessel. ► We study gas production of hydrate in porous media with huff and puff method. ► Single vertical well are used as the injection and production wells. ► Water/gas production rate and gas-to-water ratio are evaluated. ► Sensitivities of the duration of the hot water injection is analyzed.
