No one has yet shown how you can derive the curve from first principles.


If you think it's a gaussian, it derives pretty much from the Central Limit Theorem. A big enough collection of curves under certain conditions that production curves will fulfill will aggregate to a gaussian curve.


But no one thinks it is a Gaussian. Consider that this makes absolutely no sense from first principles. Gaussians extend symmetrically to the left and right of the peak. However, since oil was only discovered in the USA in 1859 and a few years before that worldwide, no way can you even begin to fit it to a Gaussian. That is, you can't fit to the tails before 1859, which is what the Gaussian expects.

A better, but not by much, approximation is to use a Log-Normal distribution, which forces a positive value (i.e. time) to go negative by taking the logarithm of the number.

But in general, the Central Limit Theorem rarely works for a stochastic time series, which is what the oil discovery profile is.

We'll gee, I bet you're a load of fun at parties. Cut me some slack here, this is my first attempt at doing modeling of any significant complexity. I understand your point, but I'm not there yet and if no one else has done it then I'd guess that you're not there yet either. To be perfectly honest, I am exceeeding the expectations of my current undergrad class with this project. I've also managed to get the other members of my project team thinking along these lines where they were completely oblivious to this problem before. I also have a chance to present this to the remainder of my class and I may make a few of them aware too. I consider that a significant (albeit humble) contribution to awareness.

So in summary.

Hey, Im just wondering has anyone got any links to artciles or sites from around the time when Hubbert made his USA prediction to critics views on his predcition etc. Just tryin to find sum references that are in context and see who actual was against it etc. Any help would be appreciated

Code:
Fifty years ago this week, on March 8, 1956, at a meeting of the American Petroleum Institute in San Antonio, Texas, M. King Hubbert, in the preprinted version of his prepared remarks, had the following statement, "According to the best currently available information, the production of petroleum and natural gas on a world scale will probably pass its climax within the order of a half century (i.e., by 2006), while for both the United States and for Texas, the peaks of production may be expected to occur with the next 10 or 15 years (i.e., 1966 to 1971)." As more and more people are learning, Lower 48 oil production, as predicted by Dr. Hubbert, peaked in 1970, and it has fallen fairly steadily since 1970.


I would go to the library and try to find out what industry magazines were published in the Oil and Gas Business and search for anything that was published shortly after the above presentation. I would imagine that a year or two after the presentation the subject would have gone off into oblivion.

Here I wouldn't be able to tell you much as I always had my head in industry literature about technology. Equations and such :-D :-D :-D

Take a look at dieoff.org. There's a lot mentioned there and was the first site that I found that started me off on the subject of PO.

I read Hubbard's stuff earlier but to be honest it did not ring an alarm loudly in my ear. The same was for my industry friends. I can honestly say that this was never discussed extensively by anyone I worked with until about 2002-2003 !!!! I mentioned PO to some friends in 2001 but the discussion died off very quickly. About 5 minutes of discussion and then we went off to do our every day engineering stuff. :) :) :)

If you listen to AM radio, you're familiar with the program MMMMMMMoneytalk. They're on AM-810 where I am right now, and they're about to discuss Hubbert's Peak. Cool 8)

OK they're about to start, they'll have Kenneth Deffeyes (pronouncing it deff-AYS) on, talking about his book, "Hubbert's Peak".

mp3's of this MMMMMmmmoneytalk program should be available, so it might be one to find and put in with the audios offered on this site.

Any chance of a summary...and, perhaps, a link to the mp3?

It sounds interesting, but I'm not going to be able to listen today.

Thanks, Jack.

AM wow!!! that would be great, oh no wait, that isn't NBC red and this isn't 1933 when AM radio was still valid. If you get a chance tell David Sarnoff about this, perhaps he can do an op-ed

Geeze, ok SSB is a much more effecient mode, but AM radio is where the talk is, it's also easiest to build an AM transmitter and receiver.

Just look up Bob Brinker and Moneytalk, you should be able to find it.

A short video of an older King Hubbert explaining peak oil. Wonderful!
