Plus we already have CO2 injection and horizontal drilling being used; still the majors are producing less.

Investment is up; drilling rig deployment is at or near record historic highs in many parts of the world -- yet new finds are not as yet delivering on the gusher(s) Yergin's thesis needs to come true.

And some experienced oil and gas CEO's are saying in public that they don't believe there are new Saudi Arabias just waiting to be discovered, with most of the world having been under the microscope for some time now.

It may be that all our new technology has ALREADY been staving off peak oil... i.e. without satellites and advanced seismic etc etc we'd have peaked long ago.

When it comes to finding stuff underground that can be extracted, at some point there will be a peak... that is inevitable. Its possible we are already good enough at finding and extracting it to have largely maxed out the planet.

I appreciate everyone taking the time to reply. I agree that the peak is coming regardless of technology - just curious if it was likely to offset the losses as BusinessWeek feels.

Are there similar charts or graphs for American oil sources?  Or perhaps for Saudi oil (I know their data is questionable)?

There are some things that you can do with EOR that will actually enhance overall oil recovery - doing liquid CO2 injection is one of them.  But it will only work in certain situations, and you need a power station that wants to find a way of getting rid of its exhaust to make it work economically. (Pumping the gas into the middle of the North Sea was a non-starter not because it wouldn't work, but because getting the gas there and liquifying it cost too much). maybe you have given me the incentive to do my "Oil Companies and Technology" Post - so I'll go write it for tomorrow.

Peak Oil theory is not just a theory, it has already been proven true in most countries. Nearly every year another country is added to the list of those who passed peak.
