We introduce an adaptive FK filter to improve the signal to noise ratio of passive seismic data. This method integrates the unique geometry of surface seismic arrays and the distribution of microseismic events induced by hydraulic fracturing. Results from both synthetic and field data show that this technique significantly improves the visibility of microseismic events in the surface recorded data. Applied together with envelope stacking, this method can efficiently locate events with various focal mechanisms.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
