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

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 ...

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

Joint seismic/electrical effective medium modelling of hydrate-bearing marine sediments and an application to the Vancouver Island margin [PDF]

, 2008
Remote determination of the hydrate content of marine sediments remains a challenging problem.In the absence of boreholes, the most commonly used approach involves the measurement of Pwavevelocities from seismic experiments.

Acoustic characterization for creep behaviors of marine sandy hydrate-bearing sediment

Scientific Reports, 2023
Marine natural gas hydrate (NGH) is a promising substitutive low-carbon energy resource, whereas NGH-production induced geoengineering concerns remain challenging. Advanced forecast of possible geoengineering risks is the fundamental for eco-friendly NGH

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 ...

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 ...

Numerical Simulation on Sand Production Based on Laboratory Gas Hydrate Production Experiment

Journal of Marine Science and Engineering, 2023
Gas from natural gas hydrate (NGH) is priced competitively with gas prices. Most marine NGH is stored in low cementing strata, which easily cause sand production problems, restricting the commercial production and environmental safety of NGH’s ...

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.

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 ...
