200 Year Supply Of Oil In One Single Shale Formation

GWPF
The Green River Formation—an assemblage of over 1,000 feet of sedimentary rocks that lie beneath parts of Colorado, Utah, and Wyoming—contains the world’s largest deposits of oil shale. USGS estimates that the Green River Formation contains about 3 trillion barrels of oil. At the midpoint of this estimate, almost half of the 3 trillion barrels of oil would be recoverable. This is an amount about equal to the entire world’s proven oil reserves."
