Material behavior and microstructure geometries at small scales strongly influence the
physical behavior at higher scales. For example, defects like cracks and dislocations evolve …

As the typical unconventional reservoir, shale gas is believed to be the most promising
alternative for the conventional resources in future energy patterns, attracting more and …

In this paper, we discuss a general multiscale model reduction framework based on
multiscale finite element methods. We give a brief overview of related multiscale methods …

Coal seam degasification by underground drilling and its effect are directly related to mining
safety and coalbed methane (CBM) recovery efficiency. The coal seam permeability is a …

Advancements in recent shale gas development technologies like creating hydraulic
fracturing have greatly improved the production of unconventional shale gas reservoirs …

In order to study the productivity dynamic evolution laws of shale gas horizontal well, a
multiscale seepage theoretical model considering the fluid–solid coupling effect is proposed …

Natural gas production from shale formations involves highly complex geological features
consisting of fractures that are embedded spatially-distributed in a matrix made of organic …

Shale gas reservoirs are uniquely characterized by extremely low values of permeability,
porosity, and complex fracture network which adequately hinders gas transfer and …

The global response of a system is often governed by the material behaviour at smaller
length scales. Investigating the system mechanics at the smallest scale does not always …

Laboratory test of coal permeability is generally conducted under the condition of gas
adsorption equilibrium, and the results contribute to an understanding of gas migration in the …
