The understanding of the phase equilibrium conditions of natural gas hydrates is essential for the estimation of potential resources of gas hydrate, which can be predicted not only from laboratory experiments but also by statistical thermodynamic models. We have developed the statistical thermodynamic model of gas hydrate based on the theory presented by van del Waals and Platteeuw (1959). We have estimated the two important parameters, #DELTA##mu#_(w, o) ~L and #DELTA#H_(w, o), using the equilibrium conditions for methane hydrate as determined by laboratory experiments. We obtained optimal values of 1247 J/mol and -4951 J/mol for these parameters, respectively.
