Rupture Propagation Imaging at Microseismic Scale

In this contribution we adopt two techniques from global seismology for imaging the rupture process of a synthetic rupture within a reservoir model of microseismic scale. We implement the Back Projection Imaging and the P wave Polarization Analysis methods and apply them to a synthetic setup similar to the Basel 1 Geothermal Reservoir, Switzerland. We use a finite-difference code to model wave field and seismograms. Our setups show that we can retrieve rupture direction, duration and speed for a 200m, horizontal, unilateral rupture corresponding to a magnitude 3.4 event, for an azimuthal well distributed seismic network and with reduced resolution for a network of poorer coverage alike.
