Abstract

The advent of wide-azimuth, long-offset land seismic data makes possible more routine application of P-wave amplitude variation with azimuth (AVZ) analysis for fracture fairway and stress-field identification and characterization. Such analysis, however, requires revisiting the processing approach which prepares the data for inversion. We expand upon an industry standard amplitude variation with offset (AVO) processing flow, which is designed to achieve this end, by incorporating azimuth into surface-consistent processes without generation of azimuthal stack volumes.
