The Bakken oil fields have been in the news again, lately....a while back, a bunch of mass emails were sent out about this, but I dismissed most of it, as bullsheeit.
The formation "supposedly" has:
8 times as much oil as Saudi Arabia
18 times as much oil as Iraq
21 times as much oil as Kuwait
22 times as much oil as Iran
500 times as much oil as Yemen
I don't believe most of the bullsheeit emails I get, so I looked up the USGS site, and this is what they say about it:

Looks like we could be energy-independent, if "somebody" got off their azz....jmho.
