In a study released by the National Institute of Oil & Gas at Rio de Janeiro State University, researchers have said that Brazil’s Subsalt Polygon, which covers its Santos and Campos offshore basins, contains at least 176 billion barrels of undiscovered, recoverable resources of oil and natural gas. That is more than 4 times the 30-40 billion already discovered in the area.
Subsalt refers to oil trapped far beneath the seabed by a layer of minerals. The Polygon covers an offshore area near Rio de Janeiro and Sao Paulo where Brazil already extracts about 85% of its oil and gas.
