- •
3D hydrofracturing behavior of heterogeneous rock was investigated.
- •
Effects of material heterogeneity and geostress difference were addressed.
- •
Mechanisms for fracture initiation and propagation were analytically interpreted.
- •
Fractal theories were used to characterize 3D hydrofracturing crack network.
- •
A threshold geostress difference for occurrence of multiple fractures was proposed.
