The glitch in the conventional peak scenario so far is that the price was supposed to skyrocket because there was nowhere left to drill. That was wrong on 2 counts, first, the price can't skyrocket and second, there will always be somewhere left to drill.
Price can't skyrocket (as much as Gold Sacks would like it too) simply because the consumer does not have unlimited funds, to pay an unlimited price, to drive unlimited miles. Here at the apparent peak and US$4 unleaded, it is still easy to conserve around the edges and the price has been adjusted to to a great extent. Mom doesn't like denying the kids a drive across town for soccer or their 3rd trip to the mall this week but she will do it. That's the top part of the wedge, the demand ceiling.
Secondly, because no extraction technique is 100% efficient, there will always be somewhere left to drill/dig/etc, it just depends on incentive. Any old peaker knows that the "rule" is that peak happens at the halfway point, which means, obviously, that half is left. The second half must come from somewhere even if it costs a lot more.
That's the bottom half of the wedge, the production floor.
The question is which way is the wedge pointing?
If it's pointing up: rising sell price matches rising cost to produce. That means the consumer is becoming more efficient, using fewer units in order to pay more per unit to achieve the same GDP. Absolute production or even production as measured as Net Energy doesn't necessarily need to rise if Utility increases, think Shanghai motorbike-pickup-trucks vs Expeditions to the Quik Sac.
But if the wedge is pointing down (and per capita production is not increasing) it means the consumer is not able to increase utility further so is being forced out of the market for the marginal barrel. And necessarily, being out of the market means falling real GDP.
The new wrinkle that I hadn't heard about in the past is declining investment. Right now we have been hearing that the incentive to invest is on shaky ground, hard to know if that is just retrenchment on the part of a few companies and NOCs or if it's a sea change in investment. Maybe because lots of the PO pundits were from the rock side of the biz we didn't hear much comment about the profit side? I don't know. It's especially notable that Matt Simmons wasn't shouting about profits instead of geology, he was a banker after all.
Some NOC exporters look to be having the same problem as the major IOCs, which is that unhappy "shareholders" are demanding short term profits after a long spell of unprofitable exploration and capital expenditures. MENA, Mexico, Venezuela and maybe Russia are all in the same boat as Shell. Russia taxes oil exports as such:
US$29.2 per tonne + 60% x (Price-US$182.5 per tonne)

Looks pretty steep, and that's before income tax.
A little of topic . . .
The biggest factor left out of the PO debate all along has been the sheep. That is the Hard Crash Peaker's conceit, that we have the inside track and the sheep will either stampede over the cliff or lay down and die. Some will of course, but better to not base your plans on it.
The legitimate object of government, is to do for a community of people, whatever they need to have done, but can not do, at all, or can not, so well do, for themselves -- in their separate, and individual capacities.
