Types of Gas Hydrates in Marine Environments and Their Thermodynamic Characteristics

Terrestrial, Atmospheric and Oceanic Sciences, 2006
The hydrates in marine environment can be grouped into two categories,diffusion gas hydrates and vent gas hydrates. The diffusion gas hydrates occur widely in an area where bottom simulation reflector (BSR) was recorded in seismic profiles, and is a ...

Investigation on Dynamic Formation, Dissociation, and Phase Transition Mechanisms of Natural Gas Hydrates in Complex Pore Structures

Applied Sciences
Dynamic phase transition of natural gas hydrates confined within complex pore–throat structures is a key factor impacting the safe and efficient development of hydrate-bearing deposits.

Determination of Priority Study Areas for Coupling CO2 Storage and CH4 Gas Hydrates Recovery in the Portuguese Offshore Area

Energies, 2015
Gas hydrates in sub-seabed sediments is an unexploited source of energy with estimated reserves larger than those of conventional oil. One of the methods for recovering methane from gas hydrates involves injection of Carbon Dioxide (CO2), causing the ...

Structure-driven CO2 selectivity and gas capacity of ionic clathrate hydrates

Scientific Reports, 2017
Ionic clathrate hydrates can selectively capture small gas molecules such as CO2, N2, CH4 and H2. We investigated CO2 + N2 mixed gas separation properties of ionic clathrate hydrates formed with tetra-n-butylammonium bromide (TBAB), tetra-n-butylammonium

Experimental Study on Sand Removal by a Downhole In Situ Spiral-Swirl Natural Gas Hydrate Coupling Separator

Applied Sciences
In natural gas hydrate exploitation, the large amount of sand production directly or indirectly leads to the low efficiency of hydrate exploitation and even the termination of exploitation.

Natural Gas Hydrates: Possible Environmental Issues [PDF]

, 2019
During the past 50 years, there has been a growing awareness of environmental issues related to energy technologies and natural resource utilization. A growing global population demands augmenting amounts of energy and goods without big discovery of conventional resources (apart from Zohr and Glafkos offshore fields in Mediterranean Sea, Egypt, and ...

Evidences for Paleo-Gas Hydrate Occurrence: What We Can Infer for the Miocene of the Northern Apennines (Italy)

Geosciences, 2019
The occurrence of seep-carbonates associated with shallow gas hydrates is increasingly documented in modern continental margins but in fossil sediments the recognition of gas hydrates is still challenging for the lack of unequivocal proxies.
