Good work Andy. What it does not show is the U.S. is the worlds
3rd largest producer of crude so it gives somewhat of a false
impression. The attached pie chart reflects that fact.

What we have seen recently is an obvious  manipulation of the
price of crude. Approval for drilling off shore and in Anwar
would tend to dampen speculation IMHO.
