Final Remarks
Final Remarks
 Sergipe-Alagoas, a traditional onshore and shallow water

producing basin, is one of the most promising ultra-deepwater
frontiers in Brazil;
 Over the last years, large discoveries of light oil, gas and
condensate were reported in the ultra-deepwater Sergipe-
Alagoas basin;
 These discoveries prove the existence of an active and efficient

petroleum system (Albian-Turonian marine source rock with
accumulations in Upper Cretaceous turbidite reservoirs);
Final Remarks
 The area on offer is in the same geological context of these

discoveries;
 Several leads analogous to the Barra, Farfan, Muriú, Moita

Bonita and Poço Verde discoveries were identified;
 The identified leads exhibit seismic facies favourable to the

presence of turbidite lobes and channels;
 Unrisked in-place volumes were evaluated at 15 billion barrels

of oil.
