Figure 2. Notice the changes in
amplitude values through the application of a typical seismic processing
sequence. This illustrates the changes for the zero-offset trace
at the top sand reflectors shown in figure
1. Observe the amplitude decreases with depth, and the major
amplitude changes due to the amplitude correction, and deconvolution.
Amplitudes from the dipping sand also change with NMO and Stack,
and move with migration to proper location.
