Natural gas resources
Stocks of naturally formed hydrocarbon gases which are usually associated with petroleum fields. Useful for heating, they are principally methane, but can be ethane, butane, or propane.
Assessment of undiscovered technically recoverable oil and gas resources of Puerto Rico and the Puerto Rico-U.S. Virgin Islands Exclusive Economic Zone, 2013 [ More info] We estimated means of 19 million barrels of undiscovered, technically recoverable oil and 244 billion cubic feet of undiscovered natural gas in this area using a geology based assessment methodology.
Assessment of undiscovered, conventional oil and gas resources of Mexico, Guatemala, and Belize, 2012 [ More info] We estimated means of 19 billion barrels of oil and 83 trillion cubic feet of undiscovered natural gas resources in 10 geologic provinces of this area using a geology-based assessment methodology.
Assessment of undiscovered, technically recoverable oil and gas resources of Armenia, 2014 [ More info] We estimated mean volumes of 1 million barrels of undiscovered, technically recoverable conventional oil and 6 billion cubic feet of undiscovered, technically recoverable conventional natural gas in this area using a geology-based assessment methodology.
