Abstract Natural Gas Hydrate (NGH) is widely discovered in silty sediments with a high
compressibility in the South China Sea. The permeability reduction in these reservoirs …

Natural gas hydrates have been investigated as a potential resource for commercially
producing gas since the 1990s. Based on the latest available data for the Shenhu area of …

An accurate description of the reservoir characteristics is essential to the precise prediction
of gas production from nature gas hydrate (NGH) deposits. In most numerical studies related …

The dissociation of hydrate plays an important role in restructuring the pore space and
controlling the permeability, which determines the gas recovery from offshore hydrate …

Natural gas hydrate (NGH) is a promising alternative energy and mainly distributes in deep
oceanic sediments. The intrinsic permeability of hydrate-bearing layers can potentially …

The gas hydrates-bearing shaly silt reservoirs have the characteristics of high reserves and
low permeability. The trial production test in South China Sea in 2020 shows that horizontal …

In 2017, China successfully conducted its first offshore gas hydrate production test by using
vertical well in the Shenhu area, achieving a total gas production of 3.09× 10 5 m 3 …

The permeability anisotropy (ie, horizontal, kr, to vertical, kz, permeability ratio) of gas
hydrate reservoirs may be a significant factor that affects hydrate dissociation and gas …

A successful gas production trial in the South China Sea in 2017 proves that low-
permeability hydrate reservoirs have great gas production potential. To improve the …

Gas production from low-permeability hydrate reservoirs is characterized by very low
efficiency. In this work, the enlarged well wall with good permeability was first proposed to …
