TGS and CGG Announce Foz do Amazonas Phase II 3D Multi-client Survey Offshore Brazil

04 Jan 2023 07:30 CET

OSLO, Norway (4 January 2023) - TGS, a global provider of energy data and
intelligence, in partnership with CGG, a global technology and HPC leader, today
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
square kilometers, 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.

Kristian Johansen, CEO at TGS commented, "We're pleased to announce the Foz do
Amazonas 3D Phase II project with our partner CGG. For TGS, this project further
strengthens our data library position in the Equatorial Margin and will be
instrumental in enabling exploration companies to have a robust subsurface
understanding in advance of future Permanent Offer rounds."

Sophie Zurquiyah, CEO at CGG, said: "With our established leadership in
geoscience solutions and unmatched experience in the Equatorial Margin, spanning
Guyana, Suriname and Brazil, our geoscientists will apply their deep regional
insight and cutting-edge imaging 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."

Early-out PSDM products will be available in Q4 2023, with final products
available from Q3 2024.

The project is supported by industry funding.
