... periods of time from some methane-hydrate accumulations by means of depressurization-induced dissociation. However, most assessments of hydrate production use simplified or reduced-scale 3D or 2D production simulations. This study used a message-passing-interface parallel code to make the first field...

.... Numerical Modeling of Gas-Hydrate Risk Gas hydrates are composed of gas molecules trapped in a solid lattice of water molecules. Dissociation of the gas hydrate occurs on heating and releases gas and water. At 1000-m water depth, which is typical for the Gumusut-Kakap field, one unit vol- ume of solid...

The MH21 Research Consortium of Japan evaluated methane-hydrate (MH) reservoirs in the eastern Nankai trough from the viewpoints of geology, geophysics, petrophysics, and reservoir/production engineering. The applicability of several MH-dissociation/-production methods to these MH reservoirs...

.../-pressure conditions. Some modeling suggests that the energy needed for dissociation could be less than 15% of the recovered energy. Natural-gas hydrates also can contain other hydrocarbons (alkanes), but may also comprise lesser amounts of other gases (mainly CO 2 , H 2 S, or N 2 ). The full-length paper...

... for production and/or only a fraction of the trapped gas can be recovered. The attractiveness of hydrates is further enhanced by the environmental desirability of natural-gas (as opposed to solid or liquid) fuels. Gas can be produced from hydrates by inducing dissociation, which also releases large amounts of H...

..., the hydrate is trapped between clay layers or other low-permeability structures. Gas hydrate exposed to the seafloor will dissociate because of the very-low hydrocarbon content in the surroundings. Though some of the released methane will be consumed by biological and chemical ecosystems, the methane reaching...
