This paper demonstrates the use of plane-wave annihilator (PWA) filters, a powerful tool for estimating dips in seismic data. Compared to conventional dip scanning methods, the PWA technique provides a more accurate and robust dip field estimate without any dip limitation. It also provides a coherency measure, useful for QC, at each analyzed point. We compare the accuracy and efficiency of two PWA dip estimation algorithms with a conventional dip scanning method on the BP EAGE 2004 velocity benchmark dataset. The estimated dip fields produced with PWA filters are very high resolution and correlate well with the seismic data.
