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 ...

The second natural gas hydrate production test in the South China Sea

China Geology, 2020
Clayey silt reservoirs bearing natural gas hydrates (NGH) are considered to be the hydrate-bearing reservoirs that boast the highest reserves but tend to be the most difficult to exploit. They are proved to be exploitable by the first NGH production test

Active Methanotrophs and Their Response to Temperature in Marine Environments: An Experimental Study

Journal of Marine Science and Engineering, 2021
Aerobic methane (CH4) oxidation plays a significant role in marine CH4 consumption. Temperature changes resulting from, for example, global warming, have been suggested to be able to influence methanotrophic communities and their CH4 oxidation capacity ...

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 ...

Numerical simulation on deposition evolution of natural gas hydrate in pipeline

You-qi chuyun, 2022
The traditional Euler-Euler fluid model is to predict the flow and deposition of two phases by approximating the hydrate particles as a fluid phase, but does not consider the effect of particle formation caused by phase change in the flow process. Herein,
