MASSY, France – CGG’s Ocean Champion has started acquiring data for Espirito Santo IV, a large BroadSeis 3D multi-client survey in deep and ultra-deepwater of the Espirito Santo basin offshore Brazil.
Acquisition should take seven months to complete, with the 10,300 sq km (3,977 sq mi) of data processed at the company’s Rio de Janeiro subsurface imaging center.
The high-end broadband sequence will include the latest 3D de-ghosting, full-waveform inversion velocity modeling and tilted transverse isotropy imaging. CGG expects to deliver fasttrack pre-stack depth migration six months after completion of the acquisition.
Jean-Georges Malcor, CEO of CGG, said the new survey would enhance industry understanding of exploration potential in this promising region ahead of an upcoming lease round.
