Was Chefurka wrong? His WEAP trend to 2100

Unread postby Cottager » Tue 26 Mar 2013, 05:11:51

I've found a forecast from 2007 year.

Looks like a big bit pesimistic. At least this graph:

According to it, it must be ~5mb/day available exports now, but actually it is better.
Seems interesting to look at such not so old forecasts :roll:

Here's his take on world population. I hope he's wrong, but he might not be:

It's pretty scary, but it's hard to make predictions about the future. We have no idea what will happen. One thing that looks like a near certainty is about 4 degrees C by mid century. That will kill a lot of people off, and peak oil is not far behind.

Yes, but look at the bright side, with half the planet dying off by mid century that's more of what ever fossil fuels are left for those that are still temporarily surviving.
The things that will destroy America are prosperity-at-any-price, peace-at-any-price, safety-first instead of duty-first, the love of soft living, and the get-rich-quick theory of life.

The post-peak decline rate is another question. The best guides we have are the performances of oil fields and countries that are known to be already in decline.

The problem with many forecasts is they attempt to extrapolate decline of the entire world from the rate of individual fields. Long after peak, new production will still come online from existing reserves, new fields and new efficiencies. Extrapolating from limited examples only shows the down side and doesn't take into account any upside. Alaska and fracking are both bumps just as russia had bumps and Mexico and Venezuela both have had declines in part due to bad management and little investment.

the North Sea basin is showing an annual decline around 10%, and the giant Cantarell field in Mexico is losing production at rates approaching 20% per year


So what? Iraq is increasing all the time, Tupi (Lula now I guess) has hardly been tapped and one day the arctic may be a placid as the pacific... not to mention there will be lots of small fields remaining to be found and maybe some big ones - though big easy ones will probably be scarce.

The other thing is that geology may hold the final number but everything else is in play, from politics to economics to social status. 10 years ago no true peaker would have predicted that driving in the US would be down 8%, the recieved wisdom was that we'd drive to survive (good song BTW) or die trying. Perhaps historically demand is only impacted x% at $x per barrel increase, but there is no rule that says it will only be affected 2x% if the price doubles, perhaps a doubling of price will reduce demand 4x% or 8x%.

There is no way to guess what's in front simply by looking back.

That is the hard part about forecasts, imagining exactly how much price will affect demand, price can not increase infinitely, so consumption in the face of increasing scarcity can not remain constant. If anything that is the biggest hole in the whole peak oil forecasting ...framework(?)


But I assume that wasn't your point in posting this was it "cottager"? Seems more of strawman construction to me, i.e., it hasn't declined, hence it never will.
