CATASTROPHIC GAS HYDRATE GROWTH UNDER SHUT-IN AND COLD START UP CONDITIONS

In this present work, capillary aided catastrophic gas hydrate growth is observed under shut-in and cold start-up conditions employing newly fabricated customized apparatus, consisting of six units of identical rocking gas hydrate cell. The observation of a capillary-aided mass-transport mechanis...
