ERROR RECOGNITION IN VELOCITY MODEL BUILDING FOR PRESTAK KIRCHOFF DEPTH MIRATION USING RMO ANALYSIS

The main purpose in seismic investigations is the correct illustration of geology in the study area. In seismic processing even small variations can have a significant impact, hiding the real signature or introducing artifacts. Velocity errors can be critical for accurate seismic representations of the modeled geology and ignoring them can damage the structural interpretation of the study area. As far as the velocity model is representative of the subsurface, Kirchoff pre-stack depth migration (PSDM) is a reasonable representation of the modeled geology.
