Natural rock joint permeability deviates from the classic fluid flow governing equations due
to the inherent fracture surface roughness (ie, contact points, spatial correlation, matching …

The characteristics of coalbed methane flow are jointly determined by the fracture and stress
environment. Previous studies conducted under conventional triaxial or uniaxial stress …

Fracture networks are of significance in the production of coalbed methane from
unconventional reservoirs. However, the complex distribution and geometry of fracture …

In the process of geothermal energy exploitation, the fracture surface of hot dry rocks (HDRs)
is easily damaged by repeated injection of cold water. To reveal the damage and flow …

Water flow experiments in single tensile and shear granite fractures were conducted to
investigate the nonlinear flow behavior. Fracture geometry parameters based on single …

Using supercritical CO 2 as fracturing medium to develop shale gas not only improve the
stimulation effect of reservoir, but also reduce CO 2 emissions. To optimise the flow of shale …

The flow behavior of the coal fracture is one of the important factors that control the
production of coal bed methane after hydraulic fracturing operation in a coal seam. In this …

Rock fractures as the main flow channels, their morphological features, and spatial
characteristics deeply influence the seepage behavior. Reservoir sandstones as a case …

Fracture and stress environments significantly affect the flow of coalbed methane. Under
stress, fracture deformation and damage occur, which change the original fracture …

It is of great significance to evaluate the fracture permeability after reservoir stimulation for
geothermal extraction. This paper is focused on evaluating the permeability of two kinds of …
