A poroelastic numerical model for simulation of hydraulic fracture propagation: Application to Upper Safa formation-Western Desert-Egypt

The hydraulic fracturing in tight sand formations has a significant importance in improving its production potential. In this study, a poroelastic numerical model is presented in order to study the reservoirs and rock mechanical properties that affect the propagation of the hydraulic fracture. The p...
