Full understanding of the compression and permeability behaviors of weakly anisotropic
sandstones is a major challenge. The present work aims to address this challenging task …

The permeability of shale in unconventional subsurface reservoirs under high-temperature
and high effective stress conditions is of great significance for evaluating the extraction …

A sound understanding of the pore-fracture system across all scales provides an in-depth
look at the intricate gas transport mechanisms in shale reservoirs. We performed a …

Exploring the dynamic mechanical properties of shale helps to understand the damage of
shale reservoirs under dynamic loading. In this paper, static Brazilian splitting experiments …

Coalbed methane, as a gas in coal seam, is a kind of potential clean energy with high
reserves. At present, there are two main types of coalbed methane extraction in China, one …

Because of coal seam excavation and periodic disturbance of back-and-forth coal cutting,
the surrounding rock is subjected to tiered cyclic unloading and loading. Based on this, a …

To study the evolution of pores and fractures in reservoir rocks under triaxial stress
conditions at the mesoscale, three-dimensional (3D) visualization of coal and shale was …

During exploitation approaching to faults structure, due to the influence of mining stress, the
rock mass inside the fault zone and between the fault and the coal pillar is prone to damage …

This study presented a three-dimensional reconstruction method for digital shale cores in
detail and examined the impact of deviatoric stress on the microscopic damage and fluid …

The high temperature and high in-situ stress geological environment can significantly affect
the mechanical properties, failure modes, and deformation characteristics of deep shale …
