Norway's TGS is set to initiate a multi-client seismic campaign, named the Pelotas Norte Phase I survey, in the Pelotas basin of southern Brazil. A vessel is scheduled to mobilize in the fourth quarter of this year to commence operations.

Survey Scope and Location

The survey will cover approximately 14,800 square kilometers across 21 exploration blocks. The majority of these blocks are located in un-held acreage, which is anticipated to be included in future bid rounds conducted by Brazilian authorities.

Objectives and Geological Significance

The primary objective of the project is to provide operators with essential 3D seismic data to evaluate potential plays within the basin. The Pelotas basin has garnered significant interest from international oil companies due to its geological similarities with proven hydrocarbon systems offshore West Africa. These similarities include the presence of organic-rich intervals from the Albian, Turonian, and Paleocene geological ages.

Operational Details

Data acquisition will be carried out by a Ramform Titan-class vessel. Operations are planned to commence in the fourth quarter of this year and are expected to continue through the third quarter of 2026.

Strategic Importance and Company Commentary

TGS states that this survey will substantially expand its existing seismic coverage in the region. The data acquired is intended to help clients gain a better understanding of the basin's geological structures and to de-risk their future exploration activities. The company notes that exploration activity in the Pelotas Norte Basin is currently accelerating.

Broader Context in Brazil

This new campaign follows two other large multi-client surveys that TGS announced earlier this year for Brazil's Equatorial Margin. With the initiation of the Pelotas Norte Phase I survey, the company will have three of its Ramform Titan-class vessels operating offshore Brazil from the end of 2025 and into 2026. The specific clients for this survey were not disclosed.
