Process name “Paint CVS Stack”
A seismic stacked section is created using Constant Velocity Stacks (CVS). The known RMS velocity is interpolated on a sample-by-sample basis for each CDP. The velocity at each window center is selected. The CVS panel nearest this velocity is chosen as the data for this window in the stacked output trace. With this tool, you can sometimes get a stack from datasets where you can’t with semblance velocity analysis.
The input trace is divided into overlapping data blocks of a set time duration. The velocity is taken at the window center. The CVS trace closest to this velocity is placed into the time window. If interpolation is selected, then the stacked trace time window is interpolated from the two nearest CVS traces to the velocity.
