U.S. Geological Survey may have grossly underestimated massive Guyana-Suriname basin potential.

The U.S. Geological Survey (USGS) assessed the potential for undiscovered conventional oil and gas fields within priority geologic provinces of South America and the Caribbean as part of the USGS World Petroleum Resources Project. Thirty-one geologic provinces were assessed in this study, which represented a complete re-assessment of the South America−Caribbean region published in 2000 (U.S. Geological Survey World Energy Assessment Team, 2000).
