From The Oil Drum: Peak Oil in 2008

Rembrandt Koppelaar, Editor of "Oil Watch Monthly," (page 1) concludes that global Peak Oil production occurred in 2008.

Global crude oil production has been on a plateau since 2004. Because oil producers were producing at maximum effort to take advantage of high oil prices, this is a clear indication of Peak Oil.

Accordingly, oil production will now begin to decline terminally.

Within a year, it is likely that oil prices will skyrocket as supply falls below demand. OPEC cuts would exacerbate the gap between supply and demand and drive prices higher.

There is discussion of Koppelaar's research at The Oil Drum.
