(WO) – TGS has introduced the beginning of its Pelotas Norte Part I multi-client 3D seismic survey offshore southern Brazil, increasing protection throughout one of many nation’s most carefully 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 seem in upcoming bid rounds.
A Ramform Titan–class vessel is scheduled to mobilize later in This autumn, with acquisition extending into Q3 2026. The survey will make the most of TGS GeoStreamer® expertise to ship high-resolution seismic information with trade funding help.
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 on account of its geological similarities with the conjugate margin and confirmed hydrocarbon techniques of West Africa.
“Exploration exercise within the Pelotas Norte basin is accelerating, with a number of main oil corporations rising their presence and dedication to the realm,” mentioned 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 giant multi-client survey bulletins in Brazil’s Equatorial Margin earlier in Q3, the Pelotas Norte Part I program brings three Ramform Titan-class vessels working offshore Brazil by means of year-end and into 2026—reinforcing the nation’s place as one of many world’s busiest offshore seismic markets.
