Seismic companies CGG, TGS and Shearwater announced a trio of new programs offshore Brazil on Jan. 4.
One program, carried out by CGG and TGS, is the second phase of the Foz do Amazonas 3D multi-client survey, which extends coverage in the Brazil Equatorial Margin. Shearwater GeoServices won the other two contracts for 4D seismic from Petrobras for the operator’s Jubarte and Tartaruga Verde fields.
According to CGG, the Foz do Amazonas 3D survey will cover 11,425 sq km.
CGG’s geologists will use technologies such as “time-lag FWI and least-squares migration to provide the high-resolution, high-fidelity data and images necessary to better understand this frontier basin,” CGG CEO Sophie Zurquiyah said in a press release.

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 Guyana 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, according to CGG.
Early-out PSDM products will be available in the fourth quarter of 2023, with final products available from the third quarter of 2024. The project is supported by industry funding.
Elsewhere offshore Brazil, Petrobras awarded Shearwater 4D survey contracts for Campos Basin fields.

The first contract is for a second 4D monitor survey over the Jubarte (Humpback) and Baleia Anã fields. Shearwater expects the project to start in the third quarter of 2023.
The second contract covers the acquisition of a high-resolution baseline 4D survey, together with gravity and magnetic measurements, over the Tartaruga Verde (Green Turtle) field. The survey is expected start in early 2024.
