June 18 (offshore-energy.biz) A multi-client 3D seismic survey is on the agenda at one of the frontier regions in Brazilian waters, with Norway’s energy data and intelligence company TGS and its joint venture (JV) partner, U.S.-headquartered SLB, at the helm of the campaign that will help boost the hydrocarbon exploration momentum in the South American country.
TGS, in joint venture with SLB, has shed light on the Pelotas Sul Phase 1 multi-client 3D seismic survey in the Pelotas Basin offshore southern Brazil, which includes a balanced mix of held and open acreage, providing opportunities for both near-term evaluation and additional sales related to future licensing rounds.
The Ramform Tethys vessel mobilized in December 2025 for the survey, covering approximately 13,500 square kilometers, with data acquisition expected to be completed in early Q3 2026. The project is perceived to mark a significant step in expanding the energy data and intelligence player’s high‑quality seismic coverage across what is described as one of Brazil’s most promising frontier regions.
