In this study, three modes of propped fracture aperture variation are proposed, and a definition of "critical aperture strain" is given to analyze the mechanism further. The non-uniform propped fracture...

The fundamental assumption of this model is that a rock joint reaches a critical state, where the shear stress and aperture is uniquely determined...

Two fracture scenarios were considered for a range of apertures: A- liquid inside a pre-existing fracture was modelled as parallel plates to determine the Laplace pressure and adhesion force. B- liquid penetrating a newly created fracture...

The results indicate that when horizontal stress difference ratio is 0.4, radial borehole fracturing has a significant guiding effect on fracture propagation behavior. Radial borehole fracturing creates fractures with larger tortuosity and aperture...
