Mechanical creep instability of nanocrystalline methane hydrates [PDF]
Physical Chemistry Chemical Physics, 2021 Fundamental creep mechanisms of nanocrystalline methane hydrates are revealed, which are of importance to evaluate the mechanical stability of gas hydrate-bearing sediments in both terrestrial and planetological environments.

Gas hydrate growth and dissociation in narrow pore networks: capillary inhibition and hysteresis phenomena [PDF]
, 2009 Marine sediments hosting gas hydrates are commonly fine-grained (silts, muds, clays) with very narrow mean pore diameters (0.1 mm). This has led to speculation that capillary phenomena could play an important role in controlling hydrate distribution in

ANALYTICAL REVIEW OF TECHNOLOGIES OF THE INDUSTRIAL DEVELOPMENT OF AQUATIC METHANOHYDRATES
Геологія і корисні копалини Світового океану, 2022 Methane hydrates are one of the most powerful reserves of unconventional sources of hydrocarbons. This is clearly evidenced by the forecast estimates of world volumes of methane in the form of gas hydrates, which many times exceed the total resources of ...

Density functional theory studies of hydrogen bonding vibrations in sI gas hydrates
New Journal of Physics, 2020 To analyze the vibrational modes of water and methane in structure I gas hydrates, we constructed a 178-atom supercell with two small cages of type 5 ^12 and six large cages of type 5 ^12 6 ^2 . We applied the density functional theory method to simulate

Nature Communications, 2016 Large methane hydrates reserves are found in mud volcanoes, but climate change may lead to methane release. Here, the authors show that methane adsorption creates overpressures leading to rapid recirculation of seawater, thus reducing the melting ...

Geosciences, 2019 Destabilization of intrapermafrost gas hydrate is one possible reason for methane emission on the Arctic shelf. The formation of these intrapermafrost gas hydrates could occur almost simultaneously with the permafrost sediments due to the occurrence of a

Sensitivity and Resolution of Controlled-Source Electromagnetic Method for Gas Hydrate Stable Zone
Energies, 2021 Natural gas hydrate is one of the most important clean energies and part of carbon cycle, due to the least carbon content. Natural gas hydrates depend on high pressure and low temperatures, located under seabed or permafrost. Small changes in temperature

Influence of temperature on methane hydrate formation [PDF]
Scientific Reports, 2017 AbstractDuring gas hydrate formation process, a phase transition of liquid water exists naturally, implying that temperature has an important influence on hydrate formation. In this study, methane hydrate was formed within the same media. The experimental system was kept at 1.45, 6.49, and 12.91 °C respectively, and then different pressurization modes ...
