Shale is a porous geological medium, hosting natural gas in its porous system. The pore
network of shale is used for multiple purposes; including storage of greenhouse gases …

Abstract Three-dimensional (3D) X-ray micro-computed tomography (μCT) has been widely
used in petroleum engineering because it can provide detailed pore structural information …

With the rapid development of horizontal well drilling and hydraulic fracturing techniques,
shale gas has become a major source of energy in recent years. However, accurately …

Carbon capture and storage (CCS) is a promising approach to simultaneously maintaining
energy security and reducing carbon dioxide (CO 2) emissions under the current energy …

With the advancement of drilling and completion technologies in unconventional reservoirs,
more extended reach wells are developed, and narrow-fracture environments are created in …

It is of great significance to study shale apparent permeability under the action of multiple
flow mechanisms and factors because shale reservoirs possess complex pore structures …

Research on the characteristics of gas flow in coal rocks is fundamentally important for
coalbed methane exploitation. Laboratory tests of prefractured coal samples may be a …

Microscopic computed tomography (Micro-CT) is used to visualize microscopic flow in
sandstone core samples during emulsion flooding. The images obtained during the …

The natural microfractures, which are widely present in shale rock, are the dominant
channels for shale gas seepage. However, most of the existing studies on gas seepage in …

Shale permeability will change with the variation of reservoir pressure and formation stress,
especially when natural fractures occur failure due to pressure and stress perturbation …
