This open access book primarily focuses on the methodologies for measuring the permeability of tight rock formations. Permeability stands as a pivotal parameter in assessing the permeability or transport capacity of tight reservoirs, exerting a significant influence on the extraction of reservoir resources. Laboratory experiments on permeability serve as a crucial means to understand the intrinsic permeability of shale. However, the permeability of shale is exceedingly low and is susceptible to influences from various experimental factors such as gas adsorption, ambient temperature, and...

This open access book delves into the realms of geotechnical engineering and solid mechanics. In order to establish fracture parameters that are both relevant and conducive to safety, the book extensively investigates the fracture mechanical properties of mode I, mode II, and mode III in brittle rock materials. Various fracture testing methods and fracture mechanics theories are employed for a comprehensive examination. To provide a theoretical interpretation of the fracture test results, the book presents detailed derivations of established fracture criteria. Additionally, new fracture...
