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.
