Figure 1: Vertical slices through the seismic amplitude volume (a) before and after (b) two passes of Kuwahara structure-oriented filtering. Notice how cross-cutting noise inconsistent with structural dip is suppressed, amplitudes consistent with structural dip are preserved, while discontinuities are sharpened with filtering. Green arrows indicate the footwall of a fault, while yellow arrows indicate folds that may be associated with pop-up features. Size of analysis window is 5 traces by 11 2-ms samples.
