Barreirinhas Basin

CGG has acquired a BroadSeis 3D multi-client deepwater seismic survey program covering over 12,000 km² of the Barreirinhas Basin in the equatorial margin of northern Brazil.

Megabar Xline
MegaBar mapThis broadband survey, which is also known as MegaBar, was acquired using the BroadSeis, tailored variable-depth streamer profile to achieve optimum resolution with the best low-noise low frequencies.

With over 50 years of operating history in Brazil, CGG is as dedicated as ever to supporting Brazil’s exploration, development and production challenges and believes that this regional seismic dataset offers an excellent opportunity to understand the geological potential of this new frontier.

A JumpStartintegrated geological and seismic project covering the Brazilian Equatorial Margins is also being undertaken by our Robertson GeoConsulting group, for a more complete understanding of the potential prospectivity of this area.
