Abstract

Summary

With a hybrid monitoring array of 15 Hz downhole sensors and lower frequency sensors on the surface, we can look in detail at the differences in rupture processes between lower magnitude seismicity usually associated with hydraulic fractures (M<0) and larger magnitude events (M>0). We find that in the dataset we examine from the Horn River Basin in NE BC, that the lower magnitude events are associated with more lubricated, slower slip, and simple rupture processes whereas the larger magnitude events are more consistent with a more complicated rupture process with less of a fluid component. These findings are important to develop an understanding of the generating processes behind larger magnitude events observed during hydraulic fracture completions.
