3D geomechanical modelling of induced seismicity: Simulated finite-source to moment tensor inversion

Modelling dynamic fault slip and seismic wavefield for production-induced seismicity in Groningen

Induced seismicity from a gas-producing region such as Groningen is believed to be caused by reservoir depletion due to long-term gas production. However, because of the complexity and uncertainty regarding the underground structure and composition, it is difficult to quantify the effect on induced seismicity due to gas production. Here we use...

Modelling episodic induced seismicity with poroelastic dynamic rupture and large-scale wavefield propagation

Modelling dynamic rupture is essential to correctly describe the process of induced seismicity. Defmod, an open-source finite-element code featuring quasi-static loading, co-seismic volumetric strain, and dynamic rupture, is used to simulate the entire chain of induced seismicity, from pressure evolution due to fluid injection and extraction,...
