Translations:Seismic sequence attribute map (SSAM)/7/en

How is the SSAM generated? To generate an average envelope-amplitude map, we start by loading the envelope-amplitude data into the workstation, along with interpreted sequence boundaries. Next, we delineate the upper and lower boundaries of the sequence of interest on the seismic data. Then we estimate the average envelope amplitude along the vertical lines within the sequence boundaries. Finally, we can contour the resulting average envelope-amplitude horizon to produce a map of the average envelope-amplitude variation within a sequence (Figure 5).
