Stratigraphic Traps in Sergipe–Alagoas Basin, NE Brazil: How Far Do Turbidite Fans Go?

Jose A. Cupertino¹, João Claudio J. Conceição¹, and Roberto C. R. Cunha¹


Traditionally, Petrobras discoveries occurred in siliciclastic rocks deposited in the Late Cretaceous during the drift phase in the South Atlantic margin (post-salt deposits). More recently, Petrobras achieved a high rate of exploration success in carbonate rocks deposited in the Lower Cretaceous in the rift phase (pre-salt reservoirs).

However, it was during the 1980-90's that the first giant fields in deep waters of the Campos Basin were discovered and delimited. These reservoirs are constituted by siliciclastic turbidite flows, where it is essential to know the relationship between tectonics and stratigraphy for their delimitation.

In the last few years, good exploratory results have been obtained in this play, now in ultra-deep waters of the Sergipe-Alagoas Basin in NE Brasil. In this talk the several discoveries will be presented and their stratigraphic components will be stressed.
