|Abstract:||Stacking velocities must be determined with extraordinary emphasis to obtain good sections, correctly interpretable from both the structural and the stratigraphic points of view. Detailed velocity analysis proved to be the most important and time-consuming processing step in the conventional CMP stacking procedure. This aspect involving high processing costs is the main drawback of the shallow seismic reflection. The Common Reflection Surface stack (CRS stack) method is a reliable alternative to the conventional CMP method, since it does not need the knowledge of a macro velocity model to produce a stacked section. In this contribution we process two dataset using both conventional CMP (with detailed velocity analyses) and CRS (without velocity analyses) stacking methods. The stacked sections, appearing very similar, prove that the CRS stack method is very a very useful tool in both shallow and ultra-shallow seismic reflection surveys.|
