This is becoming more important especially for complex areas, as the reservoirs of the Pre-Salt section of Campos and Santos Basins, over the Brazilian offshore area. In this paper, we will explore a new proposal for building a more realistic and geologically constrained velocity model and show some applicabilities for several geosciences disciplines as illumination studies, seismic processing, inversion studies, facies classifications, depth uncertainties, geomechanics, reservoir uncertainties, taking advantages using this approach. Through the images we will show the main advantages to build plausible geological velocity models, especially for the salt section above the pre-salt reservoirs.
