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. date: 1998-09 date_type: published series: SEG Technical Program Expanded Abstracts publisher: Society of Exploration Geophysicists pagerange: 964-967 pages: 2092 event_title: Society of Exploration Geophysicist 68th International Annual Exposition and Annual Meeting event_dates: September 13-18,1998 id_number: doi: 10.1190/1.1820653 isbn: 1052-3812 book_title: SEG Technical Program Expanded Abstracts 1998 official_url: https://library.seg.org/doi/abs/10.1190/1.1820653 access_IS-EPOS: limited owner: Publisher citation: Urbancic, Ted and Zinno, Richar J.
