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

Energies, 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

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.

Seismic evidence for shallow gas-escape features associated with a retreating gas hydrate zone offshore west Svalbard [PDF]

, 2012
Active gas venting occurs on the uppermost continental slope off west Svalbard, close to and upslope from the present-day intersection of the base of methane hydrate stability (BMHS) with the seabed in about 400 m water depth in the inter-fan region ...

Gas hydrate growth and dissociation in narrow pore networks: capillary inhibition and hysteresis phenomena [PDF]

, 2009
Marine sediments hosting gas hydrates are commonly fine-grained (silts, muds, clays) with very narrow mean pore diameters (0.1 mm). This has led to speculation that capillary phenomena could play an important role in controlling hydrate distribution in

Estimation of gas hydrate concentration from multi-component seismic data at sites on the continental margins of NW Svalbard and the Storegga region of Norway [PDF]

, 2008
High-resolution seismic experiments, employing arrays of closely spaced, four-component ocean-bottom seismic recorders, were conducted at a site off western Svalbard and a site on the northern margin of the Storegga slide, off Norway to investigate how ...

Widespread natural methane and oil leakage from sub-marine Arctic reservoirs

Nature Communications, 2023
Barents Sea shelf experienced >30 episodes of glaciation which scraped off layers of rocks and led to petroleum reservoirs exposed onto the seafloor. Today, such uncapped reservoirs produce strong fluxes of methane gas and oil into the ocean.

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 ...

Gas hydrate growth morphologies and their effect on the stiffness and damping of a hydrate bearing sand

, 2008
Using a specially constructed Gas Hydrate Resonant Column (GHRC), the University of Southampton explored different methods of hydrate synthesis and measured the properties of the resulting sediments, such as shear wave velocity (Vs), compressional wave ...

Effect of grain characteristics on the behaviour of disseminated methane hydrate bearing sediments. [PDF]

, 2008
Results of seismic surveys are routinely used to assess the presence of methane hydrate in deep ocean sediments. Accurate estimates of hydrate distribution and volume within the sediment are required to assess the potential of gas hydrate as an energy ...

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.
