Investigation on the Influence of Water-Shale Interaction on Stress Sensitivity of Organic-Rich Shale [PDF]

Geofluids, 2019
Shale reservoirs are characterized by low permeability and natural fractures. In the process of reservoir development, the working fluid enters the reservoir. This may result in the formation of new fractures or expansion of natural fractures. When shale reservoirs are exploited, the fluid pressure in the fracture or pore is reduced.

China organic-rich shale geologic features and special shale gas production issues

Journal of Rock Mechanics and Geotechnical Engineering, 2014
The depositional environment of organic-rich shale and the related tectonic evolution in China are rather different from those in North America. In China, organic-rich shale is not only deposited in marine environment, but also in non-marine environment:

Effect of long reaction distance on gas composition from organic-rich shale pyrolysis under high-temperature steam environment

International Journal of Coal Science & Technology
When high-temperature steam is used as a medium to pyrolyze organic-rich shale, water steam not only acts as heat transfer but also participates in the chemical reaction of organic matter pyrolysis, thus affecting the generation law and release ...
