High-pressure gas hydrates [PDF]

open access: yesPhys. Chem. Chem. Phys., 2008
It has long been known that crystalline hydrates are formed by many simple gases that do not interact strongly with water, and in most cases the gas molecules or atoms occupy 'cages' formed by a framework of water molecules. The majority of these gas hydrates adopt one of two cubic cage structures and are called clathrate hydrates.

Effects of Salinity on Formation Behavior of Methane Hydrate in Montmorillonite

open access: yesEnergies, 2020
In marine sediments, seawater influences the phase behavior of natural gas hydrate. As a porous medium, the water distribution and physical properties of montmorillonite are influenced by the salt ions in seawater.

Electrical anisotropy due to gas hydrate-filled fractures [PDF]

open access: yes, 2010
In 2006, the Indian National Gas Hydrate Program Expedition 01, or NGHP-01, discovered gas hydrate as fill in near-vertical fractures in unconsolidated sediments at several drilling sites on the Indian continental margins.

Numerical Simulation of Hydrate Decomposition during the Drilling Process of the Hydrate Reservoir in the Northern South China Sea

open access: yesEnergies, 2022
The process of drilling in natural gas hydrate reservoirs in sea areas involves problems such as hydrate decomposition and wellbore instability. To study the response behaviors of a reservoir during the drilling process, a two-dimensional numerical model

Extent of gas hydrate filled fracture planes: Implications for in situ methanogenesis and resource potential [PDF]

open access: yes, 2008
High-angle gas hydrate filled fracture planes were identified along a 31 m interval in logging while drilling images in two holes located ~11 m apart drilled during the Indian National Gas Hydrate Program Expedition 01, offshore India.

Controlled-source electromagnetic and seismic delineation of sub-seafloor fluid flow structures in a gas hydrate province, offshore Norway [PDF]

open access: yes, 2016
Deep sea pockmarks underlain by chimney-like or pipe structures that contain methane hydrate are abundant along the Norwegian continental margin. In such hydrate provinces the interaction between hydrate formation and fluid flow has significance for ...

Thermogenic methane injection via bubble transport into the upper Arctic Ocean from the hydrate-charged Vestnesa Ridge, Svalbard [PDF]

open access: yes, 2014
We use new gas-hydrate geochemistry analyses, echosounder data, and three-dimensional P-Cable seismic data to study a gas-hydrate and free-gas system in 1200 m water depth at the Vestnesa Ridge offshore NW Svalbard.

Rising methane gas bubbles form massive hydrate layers at the seafloor [PDF]

open access: yes, 2004
Extensive methane hydrate layers are formed in the near-surface sediments of the Cascadia margin. An undissociated section of such a layer was recovered at the base of a gravity core (i.e.

3-D basin-scale reconstruction of natural gas hydrate system of the Green Canyon, Gulf of Mexico [PDF]

open access: yes, 2017
Our study presents a basin-scale 3D modeling solution, quantifying and exploring gas hydrate accumulations in the marine environment around the Green Canyon (GC955) area, Gulf of Mexico.
