Abstract
Consideration is made of how a tapered Gutenburg-Richter relationship could be adapted and applied to hydraulic fracture stimulation related seismicity and used to improve data completeness. Combined with the observed self-similar source scaling behavior the recorded events are related to fracture length and surface area of individual events and cumulatively for the reservoir volume under consideration. As shown, the cumulative surface area increases by 40% by eliminating recording biases, and over 100% when considering the minimum fracture length for flow (set to 1 m). Based on these analyses, it can be suggested that a tapered Gutenburg-Richter fit provides a more robust approach to characterizing reservoir behavior that the traditional Gutenburg-Richter relationship.
