The Qiangtang Basin is the biggest petroleum-bearing basin in the Qinghai-Tibet Plateau,and is also an area of continuous permafrost in southwest China with strong similarities to other known gas-hydrate-bearing regions.Permafrost thickness is typically 60-180 m;average surface temperature ranges from -0.2 to -4.0 ℃,and the geothermal gradient is about 2.64 ℃ /100 m.

Seismic chimneys ranging in width from 200 m to 1,000 m are observed in the seismic section in the Ulleung Basin,East Sea.Gas hydrates were intensively discovered within chimney.
The Alaska North Slope comprises an area of about 400,000 km2 including prominent gas and oil fields.Gas hydrates occur widely at the Alaska North Slope.
The hydrate-based gas separation includes the hydrate formation,the hydrate recovery,and the hydrate dissociation processes.We have investigated mainly the hydrate formation in static mixing-type flow
Two limestones were selected from Southernwest of TaiWan.Those limestones were suggested formed by anaerobic oxidization of methane.But the biogeochemical processes that occur during the limestone pre
The South China Sea is located at the junction of three tectonic plates:the Eurasian,the Pacific and the Indian-Australian.The northern continental slope,the South China Sea,is well known for its pros
The depositional environment has changed greatly as the sea level gradually rised in the continental slope region of East China Sea since Late Pleistocene.
GMGS conducted the second expedition drilling of gas hydrates (GMGS2)in the northern slope of South China Sea from May to September,2013.Altogether 13 pilot holes are drilled,10 of them are logged by
Naturally occurring hydrate deposits represent a critical opportunity for conventional energy production to support increasing global demand.To produce natural gas,operators must consider viable metho
In conventional energy transportation,produced water may be emulsified in the liquid hydrocarbon phase at high pressure.If system temperature decreases due to thermal exchange with the environment,gas
There have two main sets of coal-measure source rocks in the Qiangtang Basin,which are Tumengela Formation in Triassic and Nayixiong Formation in Permian.Through field investigation and laboratory int
