Augmenting Downhole Seismic Networks with Surface Sensors to Monitor Hydraulic Fracture Stimulations for Accurate Hazard Assessment and Full Bandwidth Assessment of Scaling Relationships for Discrete

An array of 4.5 Hz geophone and FBAs recorded a sequence of seismicity during a hydraulic fracture stimualtion that culminated in a couple ~M3 events. These sensors record accelerations and velocities that can be used to show the peak ground motions that are necessary for seismic hazard studies. We discuss that using the appropriate instrumentation during these monitoring efforts is essential to being able to quantigy hazard.
