Abstract
In order to obtain fundamental data for the evaluation of permeability in methane hydrate reservoir, we have conducted an experimental study on the behavior of multiphase flow in artificial sample of marine sediment with gas hydrates. The formation rate of methane hydrate in porous media depends on the diameter of sand and the kind of porous media. In an experiment of dissociation of hydrate by the injection of hot water, the increase of permeability in methane hydrate reservoir was observed as a function of time. Furthermore, it was found that the water permeability drastically decreases as the hydrate saturation becomes higher.
