Research on the Occurrence State of Methane Molecules in Postmature Marine shales—A Case Analysis of the Lower Silurian Longmaxi Formation Shales of the Upper Yangtze Region in Southern China

Frontiers in Earth Science, 2022
The Yangtze region in southern China is endowed with abundant marine shale gas. Methane molecules exist in either adsorption state or free state in postmature marine shales, depending on the components of shales.

Three‐Dimensional Free Gas Flow Focuses Basin‐Wide Microbial Methane to Concentrated Methane Hydrate Reservoirs in Geological System

Journal of Geophysical Research: Solid Earth, 2021
We present a systematic model that links the generation, migration, phase partitioning, and accumulation of methane into a closed loop as the sediment is deposited from the seafloor and buried through the base of hydrate stability zone (BHSZ).

Upward‐Doming Zones of Gas Hydrate and Free Gas at the Bases of Gas Chimneys, New Zealand's Hikurangi Margin

Journal of Geophysical Research - Solid Earth, 2021
Focused gas migration through the gas hydrate stability zone in vertical gas conduits is a global phenomenon. The process can lead to concentrated gas hydrate formation and seafloor gas seepage, which influences seafloor biodiversity and ocean ...

Experimental Study on Influence of Gas Occurrence State on Strength of Granular Coal

Meikuang Anquan, 2020
Based on the characteristics of small cracks and large sample size of granular coal, the gas-bearing granular coal is taken as the research object, and the relationship between coal mechanical strength and gas is studied by using the firmness ...

Identification of Gas Accumulation Adjacent to the Gas Hydrate Bearing Zone by Inversion Utilizing AVO Attribute [PDF]

Journal of Petroleum Science and Technology, 2018
The presence of gas hydrate and associated gas in the Makran Accretionary Prism, offshore Iran, has been confirmed by various seismic indicators, including the bottom-simulating reflector (BSR), amplitude blanking, and bright spot. The pre-stack analysis

Coexistence of natural gas hydrate, free gas and water in the gas hydrate system in the Shenhu Area, South China Sea

China Geology, 2020
Shenhu Area is located in the Baiyun Sag of Pearl River Mouth Basin, which is on the northern continental slope of the South China Sea. Gas hydrates in this area have been intensively investigated, achieving a wide coverage of the three-dimensional ...

Prediction of Gas Hydrate Formation at Blake Ridge Using Machine Learning and Probabilistic Reservoir Simulation

Geochemistry, Geophysics, Geosystems, 2021
Methane hydrates are solid structures containing methane inside of a water lattice that form under low temperature and relatively high pressure. Appropriate hydrate‐forming conditions exist along continental shelves or are associated with permafrost ...

Shale gas content evaluation for deep strata and its variation: a case study of Weirong, Yongchuan gas fields in Sichuan Basin

Shiyou shiyan dizhi, 2022
The exploration and development of shale gas in China are recently focusing on the deep layers. However, the occurring characteristics of shale gas under high temperature and high pressure are not clear, which imposes great restrictions to deep shale gas
