(WO) – TGS has introduced the beginning of its Pelotas Norte Section I multi-client 3D seismic survey offshore southern Brazil, increasing protection throughout one of many nation’s most intently watched frontier basins forward of future licensing alternatives. The challenge will map roughly 14,800 km² throughout 21 exploration blocks, most of that are in unheld acreage anticipated to look in upcoming bid rounds.
A Ramform Titan–class vessel is scheduled to mobilize later in This fall, with acquisition extending into Q3 2026. The survey will make the most of TGS GeoStreamer® expertise to ship high-resolution seismic knowledge with business funding assist.
The Pelotas basin accommodates early-basin carbonates, passive-margin clastics, and a number of organic-rich intervals spanning the Albian, Turonian, and Paleocene, drawing operator curiosity because of its geological similarities with the conjugate margin and confirmed hydrocarbon methods of West Africa.
“Exploration exercise within the Pelotas Norte basin is accelerating, with a number of main oil firms growing their presence and dedication to the world,” stated Kristian Johansen, CEO of TGS. “This multi-client survey considerably expands our seismic protection and can assist purchasers higher perceive the basin’s buildings and derisk future drilling.”
Following two massive multi-client survey bulletins in Brazil’s Equatorial Margin earlier in Q3, the Pelotas Norte Section I program brings three Ramform Titan-class vessels working offshore Brazil by way of year-end and into 2026—reinforcing the nation’s place as one of many world’s busiest offshore seismic markets.
