Hybrid implicit–explicit XFEM simulation of injection-induced seismicity: resolving multi-scale rupture nucleation and dynamics

Abstract. This study introduces a new hybrid implicit–explicit (IMEX) time-integration method for simulating injection-induced fault reactivation within a fully coupled hydromechanical extended finite element (XFEM) framework. Modeling these systems is inherently difficult becaus...

Impact of fault aperture variation on induced seismicity at the VITO geothermal site

Abstract Mitigating induced seismicity remains a major challenge for geothermal reservoir stimulation. At the VITO geothermal site in Belgium, operations have induced seismic events with moment magnitudes up to M W 2.0 within the fractured Dinantian limestone reservoir. Numerical...
