Hydraulic fracturing volume is associated with induced earthquake productivity in the Duvernay play

Abstract

cubic meters) and that seismic productivity scales linearly with injection volume. Injection pressure and rate have an insignificant association with seismic response. Further findings suggest that geological factors play a prominent role in seismic productivity, as evidenced by spatial correlations. Together, volume and geological factors account for ~96% of the variability in the induced earthquake rate near Fox Creek. This result is quantified by a seismogenic index-modified frequency-magnitude distribution, providing a framework to forecast induced seismicity.
