The article says it's not all in One specific "localized Area", like you see in most deposits; though with all the Drilling and Logging technologies we have, I'd think it's not too difficult to recover the oil.
Some of the oil is in a mountainous region, which will probably make it a little more difficult to get... But They know it's there, at least.
Ain't that the truth. This could take care of our oil supply for years to come and get us through til more economical alternatives are ready.
The email quoted another source; saying the amount of oil, even if only 10% is recoverable/usable, could power the U.S. for 41 years straight.
