Drew, J. and White, R. S. and Wolfe, J. (2008) Microseismic event azimuth estimation: establishing a relationship between hodogram linearity and uncertainty in event azimuth. SEG Expanded Abstracts, 27. DOI 10.1190/1.3059186Full text not available from this repository.
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 error), the signal-to-noise ratio, and hodogram rectilinearity.
