The mechanism of formation and dissociation of gas hydrates in a partially saturated silica sand was investigated. In the experiment, an aluminum pressure vessel with moist F110 sand with an average porosity of 0.38 and an average water saturation of 0.52, was used. Methane hydrate was formed by introducing methane at 6.2 MPa into the sample while it was maintained at 1.1C. A depressurization induced additional hydrate formation, resulting in a slight temperature increase and continued slight pressure decline.
