The latest report on undiscovered conventional oil and gas resources outside the United States estimates that there are more undiscovered and technically recoverable natural gas and natural gas liquids (NGLs) but less oil than had previously been thought. The 18 April report, issued by the U.S. Geological Survey (USGS) as part of its World Petroleum Resource Project, estimates that there are 5606 trillion cubic feet of natural gas, compared with 4669 trillion cubic feet in the previous assessment, in 2000, and 167 billion barrels of NGLs compared with an earlier 207 billion barrels. The assessment also estimates that there are 565 billion barrels of oil compared with an earlier 649 billion. About 75% of those resources outside the United States are located in four regions: South America and the Caribbean, sub‐Saharan Africa, the Middle East and North Africa, and the Arctic provinces portion of North America, according to the new assessment.
