The U.S. Geological Survey (USGS) assessed the potential for undiscovered conventional oil and natural gas resources of Puerto Rico and the Puerto Rico–U.S. Virgin Islands Exclusive Economic Zone (EEZ; EEZ–Scan Scientific Staff, 1987) (fig. 1). The assessment was based on the postulated presence and viability of petroleum-system elements including petroleum source rocks (quality, source-rock maturation, generation, and migration), reservoir rocks (depositional environments, sequence stratigraphy, and petrophysical properties), traps (type and formation), and timing considerations. Using this geologic framework, the USGS defined three hypothetical petroleum systems and five assessment units (AUs) (table 1). This study assessed the potential for technically recoverable resources in new field discoveries; economic resources were not evaluated. Five hypothetical AUs were geologically defined to encompass those areas of the EEZ that were further evaluated for potential oil and gas resources (fig. 1): North Coast Basin AU, San Juan Basin AU, South Coast Basin AU, North Mona Basin AU, and the Muertos Deformed Belt AU. The five AUs combine to form about 13 percent of the total area of evaluation. Most of the evaluation area, including Atlantic oceanic crust, Caribbean oceanic crust, Puerto Rico Trench area, and shelf areas have no petroleum potential and were not considered further. In addition, there is no potential for oil and gas resources within the onshore area of Puerto Rico or the U.S. Virgin Islands. Using a geology-based assessment methodology, the U.S. Geological Survey estimated means of 19 million barrels of undiscovered, technically recoverable oil and 244 billion cubic feet of undiscovered natural gas in the Puerto Rico–U.S. Virgin Islands Exclusive Economic Zone.
