I’m expanding on the ideas in my earlier post – which I’m repeating here because I think it’s important and shouldn’t be lost in the middle of the CH + AD spat.
$this->bbcode_second_pass_quote('lper100km', 'D')oing some very rough calculations from the curves found in
http://tinyurl.com/32ef5ud, I estimate that the world oil consumption to 2010 is approx 1,200Gb. Colin Campbell’s estimate of 850Gb remaining recoverable lends credence to the idea that we are already well beyond the peak. That is hardly cause for complacency. Curiously, or is it merely coincidence, the quoted official estimates remaining are 1,330Gb, which places us at or very close to peak. These curves seem to suggest that the future oil remaining is in the order of 650Gb - even less optimistic than Campbell, and do seem to confirm that peak has already occurred, with deep sea drilling making little impact. It's dated from 2004, so there may have been some changes since then though I doubt that the big picture has changed very much.
It’s also highly unlikely that bau will continue smoothly until the last drop is consumed. There’s much more likelihood of economic and social turmoil well before that and it would not surprise me to see that a good part of the remainder is actually left in the ground as the resources to extract it are weakened or circumstances simply make it impossible to do so.
So a theoretical 26 years may sound comforting to some, but I suspect that can be cut in half or more before things start to go south. In any event, 26 years is nothing in the grand scheme of things, so it hardly matters.
Does anyone
really know what reserves are there, or know what past consumption has been, with any accuracy?
If these numbers are in the ballpark, then retrofitting them indicates that Peak Oil occurred sometime in 2005 - 2006.
Now the recession did not kick in until 2008, so how come there seemed to be no consequence to the arrival of PO for the two years intervening?
PO is the 50% mark of oil reserves remaining against oil consumed. It says nothing about rate of production. That is a technical issue. So it is more than conceivable that the production capacity was adequate to satisfy the increasing demand of that period, though with some difficulty as the price rose steeply for a short period. In the process though, that had the effect of depleting reserves more rapidly. Now, in recession with oil demand reduced, the reduced reserves, the increased difficulty of obtaining new supply and the questionable ability to sustain production at pre-recession levels, are all being masked.
Peak Oil and peak production do not have to coincide. Peak production to date, in my opinion, has occurred in 2008, up to two years after PO. It is possible I suppose that even that number could be surpassed in future, but with dire effects on remaining reserves and time to exhaustion.
If and when the economy starts growing again, it will be seen whether these ideas have any value.
