Methane gas hydrates, crystalline inclusion compounds formed from methane and water,
are found in marine continental margin and permafrost sediments worldwide. This article …

Natural gas hydrate is one of the most potential carbon energy resources because of its
tremendous reserves. Gas and water permeability of natural gas hydrate-bearing sediments …

Review of the literature reveals that the nature of pore‐scale interactions between gas
hydrates and porous media remains a matter of controversy. To clarify the situation, nuclear …

Permeability of the hydrate-bearing sediments critically affects the hydrate dissociation
process as well as the rate and efficiency of gas production. Reported permeability values …

Remote seismic methods, which measure the compressional wave (P wave) velocity (Vp)
and shear wave (S wave) velocity (Vs), can be used to assess the distribution and …

Shallow drilling hazard assessment consists of geological/geophysical review of drill sites to
enable the avoidance or effective mitigation of problems that can affect the safe drilling of the …

A solid understanding of the mechanical properties of hydrate-bearing sediments is
essential for the safe and economic development of methane hydrate as an energy …

In this paper, we present the current practice of investigations of seafloor instabilities and
deformation processes, based on extensive research conducted over the last years, which …

The presence of gas hydrate in oceanic sediments is mostly identified by bottom-simulating
reflectors (BSRs), reflection events with reversed polarity following the trend of the seafloor …

Clathrate hydrate is a solid crystalline compound that consists of water cages with trapped
gas molecules. Methane hydrate in permafrost and marine sediments is estimated to contain …
