The results show that fracture aperture significantly increases as the differential stress increases due to shear dilation, which...

Our results indicate that mechanical compaction and fine particles migration have opposite impacts on permeability and FND, especially in clay-rich shales. It appears that fine particle migration creates a self-propping aperture that results...

A model in 3DEC numerical modeling code was constructed using the Discrete Fracture Network (DFN) technique to explicitly create fracture systems in the model and calculate fracture apertures under longwall...

... ABSTRACT: Natural fractures aperture and porosity have a significant impact on the quality and production of naturally fractured tight reservoirs. The existence of fractures that channel fluids towards the wellbore enhances the productivity of the field. In this context, near wellbore fracture...

... ABSTRACT: There are many applications which require a fracture flow model that accounts for variations in aperture beyond surface roughness. Large-scale models and simulations of fluid flow through fractures are almost exclusively based on the cubic law (Poiseuille flow) for steady-state flow...

... as well as the resulting dilation process could lead to a strong variation of fracture apertures and significant transmissivity changes in the fracture network (Olsson and Barton 2001; Lei et al. 2014; Lei et al. 2016). Then, the radionuclides escaping from canisters may enter the groundwater system...

Owing to the relative roughness of rock surfaces, the distribution of fracture openings fundamentally controls both the conductivity and elastic responses of the medium. Implicitly, the stress-dependent fracture aperture height distribution links flow...
