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 …

Fine-grained particles (fines) commonly coexist with coarse-grained sediments that host gas
hydrate. These fines can be mobilized by liquid and gas flow during gas hydrate production …

Gas hydrate is regarded as a promising energy owing to the large carbon reserve and high
energy density. However, due to the particularity of the formation and the complexity of …

Silty-clay reservoirs are a weak point in sand production and sand control studies due to
their low economy. However, China's marine natural gas hydrates (NGH) mostly exist in silty …

The depressurization approach of methane production from a natural gas hydrate reservoir
has been identified as the most energy-efficient production approach. However, some of the …

The presence of gas hydrates (GHs) increases the stiffness and strength of marine
sediments. In elasto‐plastic constitutive models, it is common to consider GH saturation (Sh) …

The migration of fine particles in porous media has been studied for different applications,
including gas production from hydrate‐bearing sediments. The clogging behavior of fine …
