TGS Announces Pelotas Sul Phase 1 Multi-client Survey Offshore Brazil
OSLO, Norway (18 June 2026) - TGS, a global provider of energy data and intelligence, in joint venture¹ with SLB, announce the Pelotas Sul Phase 1 multi-client 3D seismic survey in the Pelotas Basin offshore southern Brazil. The survey covers approximately 13,500 square kilometers.
The Ramform Tethys mobilized for the survey in December 2025, with data acquisition expected to be completed in early Q3 2026.
The project marks a significant step in expanding TGS’ high‑quality seismic coverage across one of Brazil’s most promising frontier regions. The Pelotas Basin has seen growing interest in recent years, supported by extensive geologic analogs, including successful exploration results along the conjugate margin. The area features a diverse range of play concepts, including turbidite systems, deep‑water channels, and stratigraphic and structural traps that remain underexplored.
Pelotas Sul Phase 1 includes a balanced mix of held and open acreage, providing opportunities for both near‑term evaluation and additional sales related to future licensing rounds.
Kristian Johansen, CEO of TGS, commented: “Pelotas Sul Phase 1 will provide valuable subsurface insight and help broaden the understanding of a basin that is gaining considerable client attention. We have earlier announced Pelotas Norte, in the Northern part of the Pelotas Basin. We are very pleased to announce Pelotas Sul and support our customers as they evaluate new exploration opportunities in the southern part of the Pelotas Basin.”
¹For certain multi-client library projects, TGS invests in the project with other parties and has cooperation agreements whereby revenues and costs will be shared. TGS recognizes the contribution from the partner as contract revenues in the multi-client segment. For Q2 2026 the contract revenues from joint arrangements are expected to be approximately in line with the Q1 2026 level, when USD 32.5 million was recorded as contract revenues in the multi-client segment.
