Large scale reactor details and results for the formation and decomposition of methane hydrates via thermal stimulation dissociation

Review of natural gas hydrates as an energy resource: Prospects and challenges

“…A more detailed description of the technique to deploy this approach in the field was suggested by Cranganu [113]. Fitzgerald et al [114] have performed in situ combustion study on a laboratory scale, which achieved a lower energy efficiency as predicted by the previous simulations. Moreover, the feasibility of in situ combustion in hydrate deposits should be validated from a process safety point of view as an un-controlled combustion may lead to the release of large amount of methane.…”

Evaluation of gas production from methane hydrates using depressurization, thermal stimulation and combined methods

“…They concluded that the energy efficiency is approximately 20.6, which indicates the multiple warm-water injection would be a promising gas producing method for the hydrate reservoir. Meanwhile, Fitzgerald et al [64] calculated the net efficiency of gas production to analyze the energy efficiency of gas production from hydrate-bearing porous media using the thermal method. They also found that the energy efficiency is closely tied to the S hi , as well as to the sensible heat of hydrate sediments.…”

Experimental Investigation into the Combustion Characteristics of Propane Hydrates in Porous Media

“…Although NGH may exist in various kinds of reservoirs, such as sand, shale and clay, those hydrates in sandy reservoirs are considered the most feasible for economic exploitation [18]. Presently, much model hydrate reservoir research has been done with quartz sand [19][20][21], and here, we also adopted quartz sand and hydrate mixtures to mimic the permafrost hydrate reservoir.…”
