How much oil is estimated to be in the United States that has not been drilled yet?

Question

Places like Alaska (ANWR), Montana, Colorado, off the coast of Texas, etc.

Can you provide links to sites for facts? Thanks.

Answer 1

Not sure about the undrilled stuff but by the last estimate I saw when I was working in the industry was that you had 75 years worth of stockpile at current consumption rates.  

Answer 2

What I heard was more than all the Arab states, and South America combined. Even if this was slightly correct, why would there be hesitation? Only a liberal would know.....Or not know.
