NUMERICAL MODELING OF GAS DISSOCIATION FROM GAS HYDRATE IN POROUS MEDIA
Gas hydrates may become an alternative future energy resource as large in-place volumes exist within and beneath permafrost and in offshore environments. However, gas production potential from gas hydrate reservoirs using different production mechanisms has not yet been fully investigated. This pape...
