Paper Summary
The Cear· and Potiguar Basins on the equatorial margin of Brazil are two deepwater underexplored basins. Both have geological exploration successes, indicating working petroleum systems and potential deepwater reservoirs. PGS has undertaken an extensive series of broadband multi-sensor GeoStreamer 3D surveys to address exploration concerns and de-risk play elements in the Potiguar and Cear· Basins. In2015, the company acquired the Cear· Fortaleza survey, followed by Potiguar Aquiraz in 2016 and Potiguar Aracati in 2017, covering over 18,000 km2 in total. Potiguar Touros is currently being permitted and is scheduled for acquisition in 2019. Several major E&P companies, including Petrobras, BP and Devon, have investigated the potential on the equatorial margin in recent years. Pecem and Pitu, discovered by Petrobras in the Cear· and Potiguar Basins respectively, are the two deepwater discoveries that have given life to the exploration programs of subsequent leaseholders like Total, Wintershall and Shell.
