Petroleum System
• Generation/Maturation
- Rift Sequence
– Beginning of the generation window : Albian
– Generation peak: Cenomanian
- Drift Sequence
– Beginning of the oil generation window :
Maastrichitian
– Generation peak : Oligocene
– Conditioned to structural lows formed by
halokinesis
Petroleum System
• Migration
– Listric faults associated to salt tectonics,
unconformity surfaces and salt dome walls,
– Autochthonous conditions of migration (Presalt section)
• Traps
– Structural/stratigraphic control as salt
tectonics effects in post-rift section
– Pre-salt section prevail on structural traps
• Cap Rocks
– Calcilutites, marls, shales and evaporites

Final Remarks
After the pre-salt discoveries Santos basin has now been
considered a potential oil and gas producer
There exists four proved plays (Pre-Salt, Albian,
Late Cretaceous and Tertiary). Pre-salt play is expected to
spread to other eastern margin basin
Recent pre-salt discoveries may add huge light oil
reserves
Bid areas are close to the most important South America
consuming region (SP – RJ)
The basin has already production facilities (e.g. Merluza and
Mexilhão gas pipelines)
Final Remarks
Santos Basin is a High Potential basin.
However, it has many areas where the
exploration efforts is too small.
