Abstract

A sharp increase in the frequency of earthquakes near Fox Creek, Alberta began in December 2013 as a result of hydraulic fracturing completions in the Duvernay Formation.  Using a newly compiled hydraulic fracturing database, we explore relationships between injection parameters and seismicity response.  We find that induced earthquakes are associated with pad completions that used larger injection volumes (104-5 m3) and that seismic productivity scales linearly with injection volume.  Injection pressure and rate have limited or insignificant correlation with the seismic response.  Further findings suggest that geological susceptibilities play a prominent role in seismic productivity, as evidenced by spatial correlations in the seismicity patterns.  Together, volume and geological susceptibilities account for ~96% of the variability in the induced earthquake rate near Fox Creek.  We suggest this result is fit by a modified Gutenberg-Richter earthquake frequency-magnitude distribution which provides a conceptual framework with which to forecast induced seismicity hazard.
