Euan,
What is the total of all the fields you listed above?

I've not added up yet. Need to cross check their views on fields we know about from OECD. It will be interesting to start summing from bottom to see how far up the list you get to get an Urengoy.

Another point I would note here is that Bakhtiari considered Russian gas claims for undeveloped fields to be grossly exaggerated.

On undeveloped fields in particular, see Investor Village CWEI, messages #s 71577, 74013 and 74021, which critically review IHS data on the top 50 gas fields outside North America by reputed reserve volume. See http://www.investorvillage.com/smbd.asp?mb=2234&pt=m

My article "Largely About Access," posted on Energy Bulletin for January 14 also gives reasons for thinking that the global gas peak, at least in terms of availability to end-users, is virtually upon us. See http://www.energybulletin.net/node/47669

Euan, do you know that according to Russian law, information about total reserves of oil in Russia and in large "strategic" oil fields is considered state secret. Because of it, foreign top managers of oil companies have problems with access to some data of their own companies. Curiously, natural gas is not covered under this law. I think, it is because Gazprom holds all information anyway, and the company can control what data can become public.

Either way, we know nothing about true amounts of oil and gas in Russia. And those who know can't speak.

Either way, we know nothing about true amounts of oil and gas in Russia. And those who know can't speak.

That is why I think that the logistic (HL) method is an invaluable tool for giving us a plausible estimate for the URR (oil) in a region. Here is our Khebab/Brown (HL based) estimate for the outlook for Russian total liquids production from mature basins. The projected initial 10 year decline rate is shown. In January, 2006, after looking at Khebab's modeling work, I said that I expected to see the Russian oil production decline resuming within one to two years, although my estimated decline rate was too high. The projected range of decline rates shown on this graph is probably more accurate:

I like your model, but we cannot deny the possibility of positive surprises. Every year the Ministry of Natural Resources take a few oil/gas/ore licenses out of the black box and auction them off. What is in that black box is everybody's guess. Also, it's hard to distinguish an oil field discovered last year and one discovered in Soviet times and put on hold. And in Soviet times we employeed pretty unique techniques of exploration like seismic imaging with nuclear blasts (total 39 explosions for that purpose).
