Effects of Salinity on Formation Behavior of Methane Hydrate in Montmorillonite

Energies, 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.

Critical Review on Gas Hydrate Formation at Solid Surfaces and in Confined Spaces—Why and How Does Interfacial Regime Matter?

, 2020
Gas hydrates are crystalline solids composed of water and gases. They occur abundantly in nature and are potentially significant to industry. Solid surfaces and confined spaces strongly affect the formation of gas hydrates. Research into this particular

Data report: Seismic structure beneath the North Cascadia drilling transect of IODP Expedition 311 [PDF]

, 2006
Between 1999 and 2004, new seismic data became available for the study of gas hydrates on the northern Cascadia margin. These data consist of multi- and single-channel data with two- and partly three-dimensional subsurface coverage and were acquired and ...

The first offshore natural gas hydrate production test in South China Sea

, 2018
Natural gas hydrates (NGH) is one of key future clean energy resources. Its industrialized development will help remit the huge demand of global natural gas, relieve the increasing pressure of the environment, and play a vital role in the green ...

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

, 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.

Pore-Scale Investigation of the Electrical Property and Saturation Exponent of Archie’s Law in Hydrate-Bearing Sediments

Journal of Marine Science and Engineering, 2022
Characterizing the electrical property of hydrate-bearing sediments is essential for hydrate reservoir identification and saturation evaluation. As the major contributor to electrical conductivity, pore water is a key factor in characterizing the ...

Large-Scale Experimental Investigation of Hydrate-Based Carbon Dioxide Sequestration

Energies
Hydrate-based CO2 sequestration is a novel approach that can not only realize permanent CO2 sequestration but can also form an artificial cap to prevent its upward migration.

Characterization of Binary Hydrates Containing Methane by X-ray Diffraction and Microscopic Laser Raman Spectroscopy

Yankuang ceshi, 2021
BACKGROUND The crystal structure of natural gas hydrate mainly depends on the species and composition of guest molecules. At present, the structure and spectral characteristics of single-component hydrate are relatively clear, but the studies of multi ...

High-pressure gas hydrates [PDF]

Phys. 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.
