DOI: 10.1016/j.geothermics.2021.102200
Abstract: Abstract Injection-induced shear stimulation (commonly known as ‘hydro-shearing’) is often implemented in Enhanced Geothermal Systems (EGS) to enhance the reservoir permeability. Hydro-shearing occurs when a critically stressed pre-existing fracture (or fault) slips at an injection… read more here.
