TGS, a leading provider of energy data and intelligence, has initiated the PAMA 3D Phase 1 Survey in Brazil’s Equatorial Margin, covering 19,343 square kilometers and more than 25 future exploration blocks in the Pará-Maranhão Basin. This basin is one of the world’s largest unexplored and highly prospective regions, the company said in an Aug 19 release.
The PAMA 3D Phase 1 Survey expands TGS’ existing data coverage in the area, adding to previous surveys that covered over 60,000 square kilometers.

The Equatorial Margin has gained industry attention due to recent successes in neighboring Guyana and Suriname, driving new exploration initiatives in northern Brazil. The survey targets reservoir-quality sands within deepwater fan systems, sourced from Amazon River-related drainage, across various plays, including stratigraphic pinch-outs and anticline structures along the margin’s fold-and-thrust belt.

Kristian Johansen, Chief Executive Officer of TGS, emphasized the significance of this region, stating, “The Equatorial Margin represents one of the most exciting exploration frontiers today. With the PAMA 3D Phase 1 survey, TGS continues to provide the industry with vital data to explore and realize the potential of this underexplored region.”
The survey will use TGS’ own high-end streamer vessels for data acquisition and its imaging capacity to address the region’s complex geological challenges. Johansen highlighted that the data would be delivered through TGS’ data management solution, underscoring the company’s comprehensive capabilities. This new dataset is expected to offer critical insights for future exploration efforts in the Equatorial Margin.
