Spatial distributions in event locations and their sourceparameters (moment magnitude, seismic moment, sourceradius, P- and S-wave seismic energy release, and staticstress drop) were examined in order to provide insight intothe geometry and fracturing process associated with theStage 2 Cotton Valley (East Texas) fracture treatment ofMay 14, 1997. Events locations (79), based on P- and S-wave first arrivals and direction vectors, were obtained toan accuracy better than 24 m (9 m on average). Spatially,events occurred at two depths (2760 m and 2820 m), andranged from 260 m west to 330 m east of the treatmentwell. The events, varying in magnitude from -1.5 to -0.5,exhibited shear and non-shear failure components, asobserved in the S- to P-wave seismic energy ratios.Additionally, the ratios generally increased with distancefrom the treatment well. Scaling in seismic momentoutlined self-similar and non-similar trends, likely resultingfrom the presence of fluid. It is concluded that the analysisof microseismicity and their source characteristics have thepotential for outlining fracture behavior in the CottonValley.
