    Fault or frac? Source mechanism and B-value detection of fault fracturing - A Barnett case study

  • Original language description

    Microseismic monitoring is necessary to optimize hydraulic stimulation in unconventional reservoirs. Recognizing the difference between reactivating pre-existing joints and tectonic faults allows engineers to improve efficiency by avoiding stimulation offaults that may intersect aquifers and do not contribute to hydrocarbon production. Gutenberg and Richter (1954) proposed a relationship of size of events and number of events for a given area to be log N = A -bMs, where the slope b1 for tectonic faultearthquakes. Maxwell et al. (2009) and Downie et al. (2010) observed a slope of b2 for hydraulically stimulated fracture events. We show that source mechanism inversion of wide azimuth microseismic data acquired with buried array technology can provide this information in real time for each event. We do this on the basis that observed fracture and fault events exhibit unique source mechanisms, allowing us to calculate b values for thousands of events grouped by their source mechanism. Th
