The document discusses the petroleum potential of the eastern margin of Brazil, detailing various sedimentary basins, exploration scenarios, and recent discoveries. It presents a renewed perspective on large light oil and gas discoveries in deep and ultra-deep waters, particularly in the Sergipe-Alagoas and Campos basins. The analysis indicates significant remaining petroleum potential, particularly in under-explored areas like Pelotas, focusing on late Cretaceous turbidites and associated geological plays.

The Eastern Margin
 Area: ~ 1.5 million km2
 Passive margin basins formed
during the breakup of Western
Gondwana and opening of the
South Atlantic;
 Propagation of breakup from
South to North (130 Ma in PEL
to circa 100 Ma in PEPB);
 10 basins with salt. Only
Pelotas is devoid of salt;
 Drift mega sequences
dominated by halokinesis,
gravity tectonics and turbidite
deposition;
 Volcanism very common in the
Late Cretaceous and Eocene.
Mostly intrusive, sometimes
extrusive.

9. Four major source rock systems:
- Lacustrine freshwater in SEAL, CAMAL and JEQ (Neocomian)
- Lacustrine saline in SAN, CAM, ES (Barremian)
- Lacustrine hypersaline in SEAL (Aptian)
- Marine anoxic in ALL basins (Albian, Cenomanian, Turonian)
Several reservoir systems:
- Pre-Rift eolian/fluvial sandstones in CAMAL (Late Jurassic)
- Coquina carbonates in CAM, SAN (Barremian)
- Microbial carbonates in CAM, SAN (Aptian)
- Albian oncolitic grainstones in CAM, SAN, CAMAL (Early Albian)
- Upper Cretaceous turbidites in ALL basins (Albian to Maastrichtian)
- Cenozoic turbidites in ALL basins (Paleocene to Miocene)
Traps of all nature:
- Structural
- Stratigraphic
- Mixed structural/stratigraphic

Outline

46. - The large petroleum potential of the EMB is not restricted to the Santos and
Campos Basins;
- Large discoveries of light oil, condensate and gas (sourced from
Cretaceous marine shales) in Late Cretaceous turbidites were reported in
the SEAL. SEAL has now become one of the most promising frontiers in
ultra-deep waters;
- ES presents the potential for sub-salt discoveries associated to
allochthonous salt bodies (similar to those in GOM) in its ultra deep waters;
- In PEL attention is now focused to stratigraphic plays associated to Late
Cretaceous/Paleogene turbidites and Cretaceous marine source rocks
within a very thick drift section resting upon huge piles of seaward-dipping
reflectors (SDR);
- Bright/flat spots and stratigraphic pinch-outs/incised channels associated
to turbidite sandstones are the most common leads;
- This renewed view indicated that there is a significant petroleum potential
remaining in the EMB.
