en.Wedoany.com Reported - The joint venture between TGS and SLB (Schlumberger) has announced the launch of the Pelotas Sul Phase 1 multi-client 3D seismic survey in the Pelotas Basin, offshore southern Brazil. The project covers both held and open areas, aiming to provide data support for near-term evaluations and additional sales related to future license rounds.

The Ramform Tethys vessel commenced the survey in December 2025, covering an area of approximately 13,500 square kilometers, with data acquisition expected to be completed by early Q3 2026. The company stated that this project is a key step in expanding high-quality seismic coverage in one of Brazil's most promising frontier regions.

TGS CEO Kristian Johansen said that Pelotas Sul Phase 1 will provide valuable subsurface insights and help expand understanding of the basin. The company had previously announced the Pelotas Norte project in the northern part of the Pelotas Basin and aims to support clients in evaluating new exploration opportunities in the southern part of the basin through Pelotas Sul.

The company emphasized that interest in the Pelotas Basin has grown in recent years, driven by extensive geological analogies, including successful exploration results along the conjugate margin. The region features diverse exploration concepts, including turbidite systems, deep-water channels, and under-explored stratigraphic and structural traps.

This latest project was announced just days after TGS secured a 3D towed streamer acquisition contract from an undisclosed oil and gas company in Africa and the Middle East.
