In order to recover gas from hydrate reserves, it is necessary for heat to flow in order to dissociate the water bonds in the hydrate structure. The question of heat flow is central to any inhibitor injection, or dissociation by hot fluids because the molecules in the resulting fluid phases have more energy than those still trapped in the solid hydrate phase. The source of the energy given to the fluid molecules may be the reserve itself, the surrounding earth, or hot fluids such as steam or geothermal brines. In this work, we measured the rate of hydrate dissociation as a function of heat input, at low, constant pressure. We also measured the thermodynamic parameters of heat capacity and heat of dissociation, which we then used in two mathematical models we generated for hydrate dissociation. The more complex mathematical model (both heat and mass transfer) was shown to collapse to the simpler model (heat transfer alone controlling) for the cases of practical interest. The heat transfer controlled, moving boundary model was demonstrated to fit all of the hydrate dissociation data within 10%, with no adjustable parameters in the model. This a priori prediction of hydrate dissociation measurements represents the state-of-the-art in accuracy. We have proposed the follow-on work of measurement and modelling of the dissociation of hydrates in sediments, together with the completion of the measurement of hydrate thermal conductivity in sediment. If funded, the follow-on work should allow a quantitative prediction of the production rates of gas from hydrates. 6 refs., 2 figs.
