Visualizing AVAZ Parameter Estimates with Uncertainty Due to Noise

D030 Visualizing AVAZ Parameter Estimates with Uncertainty Due to Noise J.E. Downton* (CGG Veritas) D. Gray (CGG Veritas) & T. Zuk (CGG Veritas) SUMMARY We present a technique to estimate and visualize uncertainty due to random noise for azimuthal AVO attributes in HTI media. With this technique uncertainty can be efficiently calculated as a by-product of the AVAZ inversion. The visualization technique allows the interpreter to view simultaneously the anisotropic gradient HTI orientation and uncertainty. The uncertainty is proportional to the noise level is dependent on the geology and is influenced by the acquisition geometry. Because of the nonlinearity of
