Potiguar Basin - Brazil - 2017

Potiguar Aracati 3D GeoStreamer

Brazil equatorial margin plays with proven exploration success
Website Map for Survey Potiguar Aracati
This dataset in the underexplored deepwater Potiguar Basin in the equatorial margin of Brazil is on strike to discoveries at Pecem and Pitu and targets Cretaceous to Lower Tertiary reservoirs.
The survey images upper slope to lower slope fan channel complexes sourced by rich Cretaceous source rock. Reservoir intervals from Cretaceous to Lower Tertiary are imaged by high fidelity GeoStreamer data. Analog prospects have been drilled in the conjugate margin in West Africa and in Guyana.
Modern broadband AVO compliant signal processing with GeoStreamer data to time and depth offers the best fidelity of seismic attributes.
