文摘
- •
A combined boundary element/finite element numerical method is developed.
- •
It considers the effects of stress shadow, fluid diffusion and fracture opening and ride.
- •
The response of a hydraulic fracture/natural fracture network to injection is investigated.
- •
Simulations illustrate injection pressure variation with network deformation and permeability change.
- •
The simulations illustrate the potential for induced micro-seismicity due to slip on natural fractures.
