Simulation technology for injection-related fault and fracture reactivation and induced seismicity
The aim of the project is to develop simulation technology for injection-triggered seismic and aseismic fault reactivation.
The project will develop simulation technology for injection-induced fault reactivation, accounting for seismic and aseismic slips, as well as slip-induced permeability enhancement. The starting point is an existing open source simulation framework that is built on explicit representation of faults, and includes THM effects, but has simple constitutive laws for friction and fault permeability. The main research task will be to expand and adapt the framework to account for advanced (rate-and-state) friction laws, and to adapt discretizations and linear and non-linear solvers to facilitate efficient simulations. Tests will span from simple cases to problems from the field.
