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.

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

Conclusions 4


Outline

- 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.
