Abstract
We present the results of a detailed seismic modeling study of induced seismicity observed at the Groningen gas field, situated in the North-eastern part of the Netherlands. Seismic simulations are valuable to support the interpretation of observed earthquake waveforms recordings and to increase the understanding of the underlying source mechanics. Our results show that a significant amount of seismic energy is being trapped below the Zechstein evaporite layer situated immediately above the reservoir layer. This confirms the damping effect of the evaporites on the earthquake signal. The simulated earthquake waveforms show a reasonable resemblance with the observed data. The outcomes can further be used to invert observed data into an earthquake source mechanism and to design new seismic monitoring networks.
