Semiautomated relative picking of microseismic events

Abstract

A high‐precision semiautomated relative picking methodology is developed and applied to a dataset of microseismic events from hydraulic fracturing. Comparison with locations from manual high‐precision picking is made and found to give similar results, but with significantly faster processing times. Applying relative picking techniques improves consistency of picking between events, therefore, improving the relative locations. This results in improved resolution of the layers and faults where the microseismic events are occurring, making subsequent interpretation easier.
