Dip, Azimuth and Fault – Volume Extraction and Visualization

B013 Dip Azimuth and Fault – Volume Extraction and Visualization A. Alam* (Prime Geoscience Corporation) & J.D. Taylor (Prime Geoscience Corporation) SUMMARY We present an automatic method to estimate dip azimuth and fault continuously in a 3D seismic volume. Spectral decomposition methods provide time-continuous phase spectrum at each trace. Laterally continuous local phase surface at a fixed time indicates a reflector. The surface gradient divided by frequency and averaged over high signal-to-noise ratio frequency bands provides an estimate of time-dip and azimuth. In contrast a discontinuous local time-dip/azimuth indicates a point on a fault conflicting dips interference or noise. Inter-linked
