Applying a New Full-waveform, Migration-based Deconvolution Approach to Locating Microseismic Events in Canada

Here we present a new method of locating earthquake hypocenters that does not require the user to identify and associate P and S seismic arrivals, eliminates the use of hodogram plots and allows reliable and accurate real time processing with a hands-off approach. The whole event location process is fully or semi-automated. The new method is well suited to real time data processing as it has removed the need for manual picks and tricky association of P and S wave-modes. The method can be applied to temporary or permanent oilfield seismic sensor deployment. We apply this new deconvolution/migration approach to a real data set recorded in Canada. We compare this to the traditional method and compare the results and benefits of using the new approach. The new method yields accurate results that can be delivered in a timelier manner.
