Reactivation of natural fractures network by hydraulic fracturing [PDF]

E3S Web of Conferences, 2020
Modelling the process of induced fracture initiation, propagation and interaction with natural fractures is a very challenged task. Significant progress has been made in recent years in the development of complex fracture models to address the needs for more suitable design tools than the conventional planar fracture models.
