Improved structural imaging of current discoveries and more confident mapping of reservoir distribution and variability are available with PGS fast-track prestack time migration output from the latest Potiguar-Aracati 3-D GeoStreamer survey. Current discoveries in the area exhibit elements of both structural and stratigraphic trapping, and the data indicate a number of undrilled analogous features on trend with the established discoveries. The amplitude versus offset fidelity and compliance delivered by GeoStreamer enables confident derisking of stratigraphic plays and prospects.
