... Abstract Sustainable high fracture conductivity is a key to successful stimulation. The reduction of hydraulic fracture conductivity due to proppant deformation and crushing is frequently observed. Previous researches are based on laboratory experiments and empirical correlations, which can...

... of induced stress using seismic moment is proposed. Seismic moment is a measure of the intensity of the energy release that is detected as a microseismic event. Moment values can be related to the strains resulting from the deformation that produced the microseismic event. A simple summation of the moment...

..., the width deformation of a fracture with interfacial slip is calculated using a displacement discontinuity (DD) method. An interface crossing criterion ( Renshaw and Pollard, 1995 ) is used to determine if the hydraulic fracture crosses a particular bedding plane during height growth. Two interface...

... effective stress influences formation permeability. In addition, this experimental study reveals that changes in formation permeability, caused by both elastic and plastic deformation, are permanent and irreversible. Related pore-deformation tests using electronic microscope scanning and constant-rate...

Such stress- and time-dependent deformation of the porous structure is known to change important properties of the rock such as porosity...
