Summary

Over the last several years, there has been a dramatic increase in the volume of wastewater injected underground as a byproduct of increased natural gas production. However, the injection of wastewater into disposal wells has been implicated in some unusual seismicity that has occurred near a few of these wells. It is important to thoroughly examine seismic observations in these sequences using ‘best-in-class’ analysis techniques. In this study we reanalyzed earthquakes recorded near the Dallas-Fort Worth airport in 2008 – 2009, using detection, location and characterization techniques adapted from the nuclear test ban monitoring community for use in induced seismicity applications.
