Question: How much oil?

[wildman]

We have had a lot of discusions on oil on this forum. One key question is how much oil there really is in the US and the World. People have written everything from 20 billion barrels in the US to 100 billion barrels or more. Could people weigh in on what they believe is the true number and why?
