Offshore Brazil Equatorial Margin
2D and 3D seismic data in the Potiguar, Ceará, Barreirinhas, and Pará-Maranhão Basins
WesternGeco, in a joint venture with TGS, has more than 40,000 km of prestack depth migration (isotropic and TTI anisotropic) 2D data available in Brazil’s equatorial margin covering the Potiguar, Ceará, Barreirinhas, and Pará-Maranhão Basins.
Also available in this area is the Potiguar 3D survey, which encompasses 2,780 km2. The processing included 3D GSMP general surface multiple prediction and 3D anisotropic VTI Kirchhoff prestack depth migration.
