MHWe have carried out an experimental study on dissociation of MH (methane hydrat) by hot-water injection as a thermal stimulation method. On the basis of the experimental results, a numerical model of MH dissociation was designed to develop a gas production simulator. The numerical model consists of a 3-phase, 3-component system, such as gas, MH and water. As MH was not mobile due to its solid material, we defined the gas-water 2-phase flow with MH formation. Further, absolute permeability and relative permeability with MH formation were measured experimentally and formulated as functions of MH saturation. Using the developed simulator, we conducted history matching of laboratory-scale experiments for MH dissociation by hot-water injection.
