Perforation after filtering. Automated picking the arrivals based on cross-correlation
Perforation. Result of processing
Main difference the MicroSeismicPRM kinematic inversion from another surface microseismic monitoring approaches consists of the using the massive cross-correlation piking of arrivals and usage the optimization algorithm for simultaneous estimation the coordinates of the event and the effective velocity for each event.
