Numerical Simulation of the Influence of Natural Fractures on Hydraulic Fracture Propagation

Figure 4

Propagation processes of a hydraulic fracture under the action of a natural fracture. (a) Propagation of a hydraulic fracture along a natural fracture. (b) Propagation of a hydraulic fracture penetrating the natural fracture. (c) Propagation of a hydraulic fracture through and along a natural fracture.
