The main exploration targets in the Pará-Maranhão Basin are both structural and stratigraphic and include Late Aptian to Early Albian fluvio-deltaic sandstones, Upper and Lower Cretaceous turbidites, Paleogene fractured calcarenites and dolomites, and Oligocene turbidites. Prospects have similar characteristics to those in the Foz do Amazonas region, albeit with a different structural style, and mixed, structural, and stratigraphic accumulations are expected. Nearby wells encountered sub-commercial oil deposits proving a working hydrocarbon system and highlighting the light oil petroleum potential of this part of the Brazilian Equatorial Margin.
The survey was acquired by Polarcus Alima in 12 x 100m x 8100m configuration, with 25m flip/flop shot interval and 10s record length. Data processing through a broadband Pre-SDM workflow is underway, with Fast-Track Pre-SDM data expected to be available at the end of October and final deliverables in June 2017.
