Shearwater CEO Irene Waage Basili said: “Shearwater and TGS have a long-established relationship and we are very pleased to develop this partnership further.

“Shearwater’s Amazon Warrior is equipped with industry-leading single-sensor Qmarine technology and will provide TGS and their clients with a powerful and effective platform for the survey, ideally suited to environmental conditions offshore Brazil.”

The survey will provide contiguous 3D coverage over the prospective Brazil Round 16 blocks in the outer Campos Basin. TGS will use full waveform inversion (FWI) velocity model building and reverse time migration (RTM) advanced imaging software to create accurate and high-resolution images of the pre-salt objectives.

TGS CEO Kristian Johansen said: “With our third multi-client programme in Brazil over the past year, the Campos 3D confirms TGS’s commitment to the country and solidifies the continued expansion of our high-quality and timely exploration products in the Brazilian Salt Basins.
