Figure 2. Vertical slices through legacy data acquired over Vacuum Field, New Mexico (a) before, and (b) after edge-preserving structure-oriented filtering using the default parameters in a commercial software implementation. (c) The difference between the two, showing the desired rejection of the steeply dipping migration artifacts, but also of the higher frequency components of the seismic signal.
