A filter to improve seismic discontinuity data for fault interpretation

Abstract Seismic-discontinuity attributes quantify the degree to which neighboring seismic traces vary from each other (Bahorich and Farmer, 1995). They detect abrupt lateral changes in seismic data character caused by faults, diapirs, stratigraphic changes, and noise. An important application is to highlight fault discontinuities for seismic data interpretation. For this purpose, other discontinuities are considered noise and should be removed (Ashbridge et al., 2000; Pedersen et al., 2002; AlBinHassan and Marfurt, 2003).
