..., which is the main cause of gouge material generation (the sheared-off or broken mineral particles) from asperities of opposite fracture surfaces in contact. The gouge particles can be further crushed into even smaller pieces with increasing shear displacements or normal stresses, during which the gouge...

... vary according to a similar tendency during the directional alteration of boundary stresses, both peaking in the 30 scenario and bottoming in the 0 and 90 cases (Figure 16a). The high ratio of the far-field stresses triggers significant shear displacement in the reservoir mod- els (Figure 14...
