Nonlinear Processing Methods for Detection and Location of Microseismic Events

In this talk, I review some nonlinear processing methods from earthquake seismology and introduce new ones. The applications shown will include · Nonlinear stacking methods and detection of weak events · Nonlinear stacking methods robust to polarity reversals · Iterative detection and correction of polarity reversed traces under poor SNR conditions · Detection of polarity reversals along a seismic horizon under poor SNR conditions I will illustrate the methods using synthetic and real microseismic data examples. This talk is on joint work with my colleagues Tony Probert, Dan Raymer and Julian Drew.
