Natural gas hydrate, a potential energy resource, is attracting worldwide attention. In this
study, we propose a new method of hydrate dissociation which uses seawater and …

Multilateral well technique is a promising approach to enhance gas recovery, especially in
heterogeneous hydrate reservoirs with underlying free gas. However, little is known about …

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 …

Multi-well systems can increase the drainage area and hence enhance the productivity of
natural gas hydrate (NGH) production. Fundamentally, the double-well system is the key and …

Hydrate reservoirs with underlying gas are promising for commercial exploitation because
the dual-gas co-production from hydrate and underlying free-gas zones is expected to …

Production tests in marine methane-bearing sediments have been carried out worldwide.
Pilot horizontal well tests have exhibited the potential of using horizontal well …

Before performing commercial scale production of natural gas hydrates (NGHs), it is
inevitable to estimate the productivity, production period, optimal operation parameters, and …

The production trials in the Shenhu Area have proved that commercial level of gas
production might be also obtained from low-permeable silty clayey-bearing hydrates as well …

Low productivity is the key to restrict the commercial development of hydrates. Due to the
advantage of integration, the multi-well pattern is a promising way to obtain high gas …

In this study, a multilayer gas hydrate reservoir model was implemented based on the
geological conditions of the Shenhu area in the South China Sea (SHCS) to predict the …
