Brazil’s Subsalt Polygon, an offshore area that has already yielded some of the world’s largest recent oil finds, may hold enough undiscovered petroleum and gas to supply the world’s current oil needs for more than five years, researchers said.
The Polygon, which covers most of Brazil’s Santos and Campos offshore sedimentary basins, contains at least 176 billion barrels of undiscovered, recoverable resources of oil and natural gas (barrels of oil equivalent), according to study released last week by Cleveland Jones and Hernane Chaves of the National Institute of Oil and Gas (INOG) at Rio de Janeiro-State University.
That is more than four times the 30 billion to 40 billion boe already discovered in the area.
