In 2007, Mexico was supplying America with 1.3 mbpd, making it effectively America's 3rd largest supplier. However, like much of the developed world, America has shrank the flubby ballast in response to high oil price overdose. As we can see from the graph below...
And let's not forget that non-OPEC total liquids has been kicking ass; that we have our friendly neighbor to the north, Canada, who in good time pick up the slack where Mexico is leaving off (with unpardonable environmental sins, of course). So I say... let Canatrell die, because with 700,000 bpd to date, it can't hurt things much more.
In actuality, there is one country that needs Canatrell badly: Mexico. This impoverished nation receives 40% of its federal budget through oil revenues. With declining oil revenue, Mexico is still loaded with poverty, illiteracy, gangs, drug wars and guns. Somebody might want to tell Dr. Wirth he may want to reconsider his location for a peak oil sustainability.
