The integration of regional 3D seismic, well logs, cores, and biostratigraphic data gathered in a sequence stratigraphic approach provide a basis for interpreting the Oligo-Miocene and Miocene system as a whole. This stratigraphic interval, which contains the most of oil reserves in Campos basin turbidites, was divided into third and fourth order sequences and mapped across the shelf, slope, and basin.

The characteristic depositional geometries recognized in seismic sections are: (1) shelf-edge prograding delta complex; (2) shelf breaching incised valleys; (3) slope erosive bypass zone, which has straight shallow channels and canyons; (4) braided sandy submarine channels filling fault-related...
