CGG and TGS announced the second phase of the Foz do Amazonas 3D multi-client survey, located in the offshore Brazil Equatorial Margin. This survey, covering 11,425 sq km, will broaden the region's 3D coverage and deliver additional high-quality data essential for the exploration efforts in the basin. Existing 2D data and adjacent 3D data indicate the presence of reservoir depositional fairways in this location which overlies a source interval contemporaneous with the Guyana Basin petroleum system.

Basin model studies predict a mature Early Cretaceous petroleum system with extensive regional reservoir distribution. The nearby Zaedyus discovery in French Guiana and the Narina and Venus wildcat discoveries on the conjugate margins of Liberia and Sierra Leone support resource potential in the Foz do Amazonas Basin.
