Seismic Edge Detection Using Generalized Hilbert Transform

P627 SEISMIC EDGE DETECTION USING GENERALIZED HILBERT TRANSFORM Abstract 1 We introduce a new algorithm DETECT for highlighting discontinuities such as faults and channels in 3D seismic data sets. Based on a novel generalized Hilbert transform (GHT) the DETECT algorithm is capable of capturing subtle changes in recorded seismic wavefields. Results produced by DETECT are of higher resolution than those obtained by other leading commercial packages. Introduction Faults and channels could manifest themselves by abrupt or gradual changes in 3D seismic data. When changes are abrupt there are several published edge-detection methods such as coherence cube (Bahorich and Farmer 1995)
