The Koppelaar paper cannot be taken seriously. Look at the graph on p. 23. The 1% and 2% growth "curves" are not exponential as they should, they are linear!

Read the estimates and specific information on the various countries. The usual official optimistic talk about raising the production is taken at its face value. Oil producing countries are ussually utterly reluctant to admit depletion and keep talking about fancy new projects that will boost production and the need of new investments. This is exactly why ASPO is there and why Simmons, Campbell and others have made their own estimates. The ASPO liquids curve is still the most realistic.

By the way, CGES has nice table on OPEC production and spare capacity. You can see that only the Saudis claim any reserve capacity - should we believe them? (CGES: Centre for Global Energy Studies
"CGES ESTIMATE OF OPEC PRODUCTION"

The curves are close to linear.  I held a straightedge up against the 2% curve, and there is a definite slight upward curvature.
Sorry, ericy (and Rembrandt), you are right. Calculated it. The time scale is short.

But I checked the Russian oil situation and found this: http://www.neftegaz.ru/analit/reviews.php?id=518

It is dated 8/11 2005 and is written by Tatjana Zaharova. It cites FAE (Federal Energy Agency) chief Oganesjan saying that during the three previous years the Russian oil production grew about 10% a year. It should grow a little this year but the growth will slow down and stabilize in 2006. (We know from the recent statistics that the production is already stabilizing this year).

The article states that the Russian Ministry of Natural Resources has a more optimistic prognosis that gives a lot of growth up to 2010. But counters that quoting Jan Kapitski from Chevron/Texaco. He says that the growth potential of the Russian energy sector has practically run out.

In fact the Russians has signalled peaking production for some time now. It is already a great difference to go from 10% growth to zero growth. That is almost 1 million bpd missed increase or 1% of the world production or 50% of the average projected world supply increase of 2%. If Russia goes to 5% decline it will take away 75% of the projected 2% growth. So we see how extremely difficult it is to make these estimates and where the error sources are.  

Here we have an example of an optimistic and a pessimistic prognosis. The difference is significant and the reality seems to be on the darker side...

Well you don't have to take it seriously. It's an estimation trying to factor in a lot of things. Ofcourse it's not the truth but i think i have come close enough. Closer then ODAC and CERA to my opinion.

Besides that its a draft version, lots of stuff still needs to be added. And as answered before those 2 curves are not linear. As for depletion i usually factor in either historic values or data from specific fields declining. Could be that some of the things that get in the paper are too optimistic (for instance 10% Cantarell decline). But who knows? You think it is better to just make some sort of quesstimate based on thin air?

How come the ASPO liquids curve is the most realistic? Based on what? ASPO hardly produced any data to prove that curve to be true. Im still waiting on their database to come online. Until i see real figures i don't take the ASPO outlook seriously.

It is quite possible that Saudi-Arabie has 500.000 to 1 million barrels of heavy crude spare capacity. We just don't know.

ASPO uses the Hubbert methodology with the depletion midpoint and production curve approach. Using the historical depletion data we cannot predict the turning points, ie. the peaking of individual fields and countries. The turning points are important as we see in Russia.

The peaking and starting of production decline makes huge difference in the future projections. If we project that a country will increase production three years by 5% a year, but in reality it starts to decline by 5%, it means that the production will be 31% lower than projected. Note: three years, 5% and 31%. If this kind of turn happens, it will crush all predictions for that oil area. And these kind of turns have happened. They have been quite a shock for those countries (take Argentine), especially if they coincide with bad price fluctuations. If investments, economic activity and economic policy is geared for continuing oil production growth, the peaking will mean that the economy falls flat down. That is why the peak is so interesting.

We can really see kind of "Hubbert phases" in many oil producing countries:  an oil euphoria when the curve goes exponential and wild projections of the oil industry growing and money flowing in are made. Liberal economic policy is adopted, currency revalues, importing stuff and taking loan becomes cheap and everbody has fun. At his moment the production peaks, without real warning (OK, some oil engineers may have hinted something). At this moment the oil officials usually make some optimistic statements of increasing investment and boosting production next year because it has been rising before. The plateau is usually not long (it might be less than a year) and the decline begins. The Hubbert curve is mostly more or less symmetric and the oil hangover begins. The drop is steepest in the beginning and the gap of expectations and reality widens rapidly. Nobody has fun any more. Currency collapses, debt becomes a burden, stocks and real estate lose their value. But nobody connects this to the oil depletion. So no lessons are learned. but some rioting is done.    

And the things you describe did not happen in the US because why?  We worked a deal with the Saudis to pay for cheap oil with the promise of reinvestment of petro-dollars in our securities markets?
If you like the ASPO curve, you need an explanation for why, given that Campbell has gotten the date of peak wrong so often before, he is going to be right this time. Also, the ASPO curve is based on a database that is not publicly accessible, so there is no way to replicate it or properly critique it.
What evidence makes you believe that ASPO is currently using any database? Earlier, you said ASPO was using the Petroconsultants DB, but Petroconsultants was acquired by IHS in 1996. Do you have any evidence to show that ASPO is currently purchasing information from IHS?

Even if ASPO is using a DB, there's something wrong with it. ASPO is currently predicting production of 82mbd for 2005 (see the Sept. 2005 newsletter at www.peakoil.ie), even though the DOE has production for the first six months of 2005 at 84.3mbd. The prediction is already wrong.

In Campbell's 1997 book "The Coming Oil Crisis" he details using the Petroconsultants database (along with a fulsome dedication to the PetroConsultants founder Harry Wassall). I speculate Campbell still had access as a favor, rather than paying after he was no longer with big companies. Also see Lynch's comments here, I do not know what ASPO is currently relying on - there is a rather content-free discussion here.
