Environmental and technical issues associated with hydraulic fracturing fluid leak‐off and its
low recovery in clay‐rich shale reservoirs has challenged the energy sector. One of the main …

Gas sorption in coal, in particular CO 2, is known to cause swelling and internal structural
change or damage. For instance, CO 2 adsorption on coal causes swelling which in turn can …

Accurate multiphysics modeling is necessary to simulate and predict the long-term behavior
of subsurface porous rocks. Despite decades of modeling subsurface multiphysics …

Coupled multiphysics constitutive models are generally developed based on macro-(core)
scale measurements often without an in-depth knowledge of involved micro-scale …

Clay swelling due to the rock-water reaction occurs commonly during the fracturing of
shales. Lots of experiments have been conducted to shed a light on the role of clay swelling …

In shale development, water‐based liquids are injected into the formations. In this process,
water can interact with shales, especially with clay content. The interaction can lead to some …

Despite significant advances in micro-scale measurement techniques for investigations in
subsurface energy-bearing geomaterials, they have been unable to incorporate subsurface …

Laboratory testing is an efficient way to study the deformation and failure mechanisms of
outburst coal. However, existing devices can only perform static loading tests on gas …

This work presents the results of an investigation on the study of fracture pattern in coal
under induced tensile stresses using image processing techniques. Several high-speed …

The investigation of the effect of hydration swelling on induced fracture generation and the
resulted permeability in shale has considerably expanded in recent years. However, only a …
