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.
