Understanding the effects of mineral composition on geomechanical characteristics is critical
in order to design and optimize the hydraulic fracturing necessary for shale gas reservoir …

Unconventional resources like shale gas has been the focus of intense research and
development for two decades. Apart from intrinsic geologic factors that control the gas shale …

A new poroelastic damage model is developed in the paper to describe the macroscopic
failure of rock materials due to microcrack nucleation and propagation based on a multiscale …

Rock fracture toughness is a critical parameter for optimizing reservoir stimulation during
deep resource extraction. This index characterizes the in situ resistance of rocks to fracture …

Multi-stage fracturing of horizontal wells to recover shale gas has attracted substantial
renewed interest in the physical and mechanical characteristics of shale. The mechanical …

Shear-sliding mode fracture, ie, mode II fracture, is a very common rupture mode of layered
rocks. To achieve a better understanding of the anisotropy in the real mode II fracture, which …

The safe and efficient development of ultra-deep shale gas deeper than 4500 m is closely
related to the comprehensive evaluation of the mechanical behavior, brittleness and …

Shales with a laminated structure typically exhibit inherent anisotropy and strong brittleness,
resulting in complex failure patterns and fracture evolution during hydraulic fracturing. To …

The influence of combining the inherent anisotropy and fatigue loading on shale's
mechanical behaviors is rarely investigated. To study the anisotropic fatigue behaviors of …

The inherent anisotropy is the most important structural feature of shale. Most research on
the mechanical behavior of shale has focused on its anisotropic strength, deformation and …
