What is Effect of Damage Zones Around Fault Core on Failure Development During Fluid Injection Into Porous Reservoirs about?

Fault zones (FZ) in porous reservoirs used for diverse underground activities are complex and heterogeneous geological systems generally constituted of one (or several) fault cores (FC) surrounded by damage zones (DZ). The latter compartment is characterized by a distribution of fractures, which can strongly affect the sustainable injection pressure, especially when the injection operation is performed in the vicinity of a FZ. This study aims at considering the effect of a realistic FZ structure on shear failure initiation and tendency during fluid injection into porous reservoirs, under extensional and compressional stress regimes. Fracture networks observed from the outcrops at the Cirques de Navacelles, were incorporated in the analysis to compute the distribution of hydro-poro-mechanical properties within the FZ. A hydromechanical simulation for geological model containing the FZ is proposed to study the reservoir behavior. Comparisons between homogeneous (HO-without DZ) and heterogeneous (HE-with DZ) cases for the most critically fracture orientation, were made in terms of the initiation and development of shear failure. We show that taking into account the DZ generally leads
