Chart on this page seems to predict peak oil around 2010. That's only 4 years away. In your opinion, is tha realistic?

2010 might actually be optimistic. There are several respected commentators who argue that peak already occurred last year.

Broadly, there seem to be two approaches to figuring out the timing of peak oil. The first, the “bottom up” approach used by Matthew Simmons, Chris Skrebowski etc. works field by field to estimate what current production levels are, add new production coming on-line and subtract current depletion rates. Skrebowski’s view is that peak oil will most likely occur no later than 2010 if everything goes perfectly; but if there’s some major geopolitical disruption before then (war in Iran, major hurricane, etc.) it will likely happen sooner. CERA also uses this approach to come up with its estimate of a plateau between 2030 and 2040, but greatly underestimates decline rates of current fields, according to people familiar with their report.

The other approach uses petroleum geologist M. King Hubbert’s methodology. In 1956, Hubbert accurately predicted that U.S. oil production would peak between 1965 and 1970 (it peaked in 1970). At the time, he made his prediction based on a range of accepted estimates of ultimate recoverable reserves. In his book Beyond Oil, Kenneth Deffeyes, a one-time colleague of Hubbert, used a simplified version of Hubbert’s methodology he called “Hubbert Linearization” which derives the ultimate recoverable reserves (and hence the peak) not from reserve estimates but from cumulative production to date.

The main theorists who are using the linearization method are Deffeyes and several contributors to the Oil Drum website (www.oildrum.com)—Stuart Staniford, Jeffrey Brown (an independent petroleum geologist who goes by the screen name Westexas) and “Khebab”. Based on this approach, Deffeyes quite confidently says that peak oil has already occurred, in December of last year (amended from his original projection of Thanksgiving 2005). Brown and “Khebab” agree with him. They have done work showing that if using the Hubbert Linearization technique, one could have predicted post 1970 U.S. oil production with an accuracy of 99% using only data available up until 1970.
