Santos Basin ŚBrazil Ś
BM-S-50/52 3D
Pre-salt trend and adjacent to the most prolific fields and discoveries in
northern Santos Basin.
The hydrocarbon plays within the BMS-50/52 survey area are: A. Post-Salt: Albian limestones;
Upper Cretaceous to Lower Tertiary turbidites in subtle traps; B. Rift/Pre-rift sanstones and
basalts in the central-western area and, C. Sag/Rift Aptian pre-salt microbial limestones.
By analogy with other areas in Santos, the BMS-50/52 area has a large hydrocarbon exploration
potential, with possibilities for significant light-oil discoveries. Most important trends are the
pre-salt targets: Sagitario trend and the Carcará-Itaipava trend.
Pre-salt exploration trends in the southern part of the survey area are the lowest-risk, most
attractive opportunities and the GeoStreamerŭseismic data (Ph II) affords improved sub-salt
imaging and identification of potential reservoir sweep-spots.
