America's Largest Oil Fields
The Eagle Ford and Bakken Shale fields are already leading an American energy revolution, raising output almost 40 percent for the first time in decades. But the newly discovered Spraberry/Wolfcamp shale play near Midland, Texas could be even larger. Early estimate from Pioneer Natural Resources are than it could contain 50 billion barrels of recoverable oil, which would make it the second largest in the world, behind only the legendary Ghawar in Saudi Arabia.
The remainder of the top 16 are all in Texas, California, Alaska and the Gulf of Mexico, including the deceptively named Delaware Basin, which straddles West Texas and New Mexico. Texas will undoubtedly develop its oil resources. California may not.
