Microseismic event azimuth estimation: Establishing a relationship between hodogram linearity and uncertainty in event azimuth
2008
SEG Technical Program Expanded Abstracts 2008
unpublished
For microseismic data monitored and detected by a downhole vertical array, the polarization, or hodogram information, is needed to determine the event azimuth. To optimally weight when averaging over multiple measurements, we require knowledge of the uncertainties associated with each estimate. We discuss data acquired during a hydraulic stimulation. Using both synthetic data and observed events, by experiment we establish a relationship between the uncertainty in the estimated azimuth (or
