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

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:

Empirical Determination of the Effective Solid Modulus in Organic-Rich Shales

Scientific Reports, 2022
Abstract Calculating the change in the saturated bulk modulus of a saturated rock as fluid properties change requires a priori selection of an effective bulk modulus of the solid constituents. When mineral moduli are similar, theoretical bounds on the solid modulus are tight.
