Traversing the entire margin of northern Brazil from Foz do Amazonas south to Espirito Santo, Greater BrasilSPAN is a multi-basin regional seismic and potential field study of Brazil’s equatorial frontier. The program was designed to provide a comprehensive deep-basin framework and a model for the hydrocarbon potential of the region.

Comprised of 3 phases, the program totals more than 34,000 km of data acquired since 2009. Greater BrasilSPAN ties to the conjugate transform margin of Equatorial West Africa where significant discoveries have recently been made and correlates paleo-tectonic “fits” with our AfricaSPANdatasets. Using this data, operators have begun to identify similar petroleum systems and structural geometries as well as differences in the evolutions of the basins. These new insights are helping operators high grade their portfolios in these highly prospective regions.

  • Improve knowledge of the development of the Amazon delta
  • Understand the Continental to Ocean Boundary transition
  • Provide greater insight into the region’s exploration potential
  • Unprecedented deep focus: 10,000 m offsets and 40km depth images
  • Area’s first fully consistent regional, depth-imaged dataset
  • Better delineation of the location and nature of fracture zones
  • Ties and transects key structural and depositional features
