A method comprises receiving 911 locations of microseismic events associated with a fracturing operation performed in a geologic environment; determining 921 an individual correlation exponent for one of the microseismic events based at least in part on distances where each of the distances is between the location of the one microseismic event and a location of another one of the microseismic events; and, based at least in part on the individual correlation exponent, associating 931 the one of the microseismic events with a fracture generated or activated by the fracturing operation. A plurality of b-value adjusted D-values are determined for corresponding individual microseismic events associated with one or more fracturing operations. The individual correlation exponent may be determined using a singularity spectrum analysis. The method may comprise filtering the individual correlation exponents to generate a group of events. |
