Barbara:
Thing is, do those take into account if American was to start a drilling and exploration frenzy, say right after E2004? You see, right or wrong, I get more and more convinced we are in the Middle East for the oil.
Yes, it does take increased effort to drill and explore into account. The high probability is that we have already discovered substantially all the cheap oil that is available, and more effort will not pay off. There are some known undeveloped resources, and it is assumed those will be developed; the thing is, that increased production will not make up for the declining production of other fields already near tap-out.
I believe you are right about us being in the Middle East for the oil, but think about what that really means. 2010 (or thereabouts) is when a
natural oil shortage will occur, but we've already seen one artificial one. We will hit the wall no later than that, but we could hit it earlier, if something happens to disrupt production levels -- like a major catastrophe in the Persian Gulf. As things stand now, and provided we're willing to go on dying for it
ad infinitum, American companies control Iraq's oil production, and as long as we can count on Saudi Arabia, too, we've got a way to increase production to meet our increasing demand until the global production peak itself.
