Following the recent major discoveries in West Africa, a new focus has been placed on the conjugate margin in northern Brazil, where over the entire 2,200 km margin only 20 wells have been drilled in water depths greater than 500m. Using the analogy from equatorial African discoveries, it appears that the highest potential may be in the deep waters on the slope and continental rise of the Brazilian margin. ION’s Greater BrasilSPAN™ data is being used to identify and map new plays similar to those currently being drilled on the African margin.
