The oil actually in the ground will be an even smaller proportion since the US territory and offshore has been intensively drilled for oil.


However under changed economics (higher oil prices), oil shale in Colorado and Wyoming could become economic. The resource is more than 2 trillion barrels and dwarfs other resources. There is enough oil in these rocks to keep the US going for a thousand years at current utilization rates. Of course extraction has significant economic and environmental issues.
