Experimental Study of Methane Hydrates in Coal

E3S Web of Conferences, 2017
The possibility of gas hydrate formation in porous space of coal has been studied. The experiments conducted have proven the possibility of methane gas hydrate formation in moist coal. It has been demonstrated that the decomposition points of methane gas

Discrete element analysis of macro- and micro-mechanical properties of methane hydrate-bearing clay under different salinities

Yantu gongcheng xuebao
The mechanical behavior of methane hydrate bearing soil is closely related to the characteristics of hydrate phase equilibrium. Compared with sand, clay has smaller pore size and the pore size has a great influence on the characteristics of hydrate phase

Dissociating Gas Hydrate Beneath the Hydrate Stability Zone

Geophysical Research Letters
Vast amounts of carbon are stored beneath the seafloor in the form of methane hydrate. Hydrate is stable at moderate pressure and low temperature at a depth extending several hundred meters beneath the seafloor to the base of gas hydrate stability (BGHS)
