In this study we examine the role of various types of failures associated with a tight sand hydraulic fracture treatment, utilizing moment tensor inversion and source parameter analysis of recorded microsiesmic events. Based on nearest neighbor statistics, events are grouped into near treatment well and fracture extension regions, and used to outline a discrete fracture network (DFN) and the spatial-temporal development of the DFN within the volumes. These results are further used to establish a geomechanical model to assess the permeability associated with the treatment, which is further used to estimate the Stimulated Reservoir Volume (SRV) associated with the treatment program and possibly enhance calculations for productivity.
