Figure 2. 3D Prospective view across Pico do Jaragua and Morro da Igreja region to demonstrate significant amplitude  anomalies at the Santonian and Oligocene levels. Level based on the WAZ ABM intermediate 3D. An anomaly at the Santonian level on the flank of the Pico do Jaragua salt diapir (seen on the left of Figure 2, at depth) was seen  in a dataset purchased during 2008 and remains very well developed on this new data. The amplitudes show the same strong  concordance to depth, which is interpreted to be the result of a hydrocarbon fluid contact and a direct indication of hydrocarbons  (‘DHI’). At the Oligocene level around the Morro da Igreja salt diapir (seen on the right Figure 2 in the shallow) there are also strong  amplitude anomalies that rim the salt body which, although in part are faulted, show concordance to depth. This relationship with  amplitude to depth provides strong DHI, which helps to reduce risk and allow better quantification of potential volumes ahead of drilling.  The improved quality of the intermediate MAZ 3D seismic data has also facilitated mapping and interpretation to commence at  the pre-salt level. Figure 3 on the following page demonstrates the current mapping at this level with clearly defined structural  high trends where there are a number of sizeable closures.
