While crude oil prices surged during the first decade of the new millennium, oil reserves increased only slightly, so we may be edging closer to the peak.
Critics of the Peak Oil concept are roughly divided into two camps. They either reject the whole theory and find a lot of reasons why oil will continue to flow, or they criticize the reserve assumptions Peak Oil scientists use. To criticize the underlying oil reserve estimates, you either tell people that we will find more oil – this is what USGS tells us: There are 0.9 trillion barrels of crude on earth we haven’t yet discovered – or that we will get more oil out of our existing fields or – best of all – just claim that both will happen.
This post deals with the assumption that there is a lot of oil and that surging prices will lead to more exploration and hence to more proven reserves, to more oil we can produce. Let’s test this with real-world figures.
Once again, I focus on the period from 2002 until 2007, a period of surging crude oil prices. In 2002, crude was traded for $26.16, while in 2007 the price was up to $72.20. According to the theory, which is nothing more than the classical boom-and-bust theory, higher prices should lead to more crude oil discoveries as more and more money is invested into exploration efforts, which will lead to new discoveries.
This view of the world clearly clashes with Peak Oil theory. As Deffeyes explained, oil is a finite resource and there are good reasons to believe that most of it is already found. Peak Oil claims that we are halfway through, but if there is more oil we can add to our reserves, and with more I mean an awful lot more oil, this will – according to the theory – postpone Peak Oil, the global production peak.
To put it into perspective, the oil price increased from 2002 until 2007 by an astonishing 176%, but what happened to global proven crude oil reserves? According to the boom-and-bust believers, reserves must have kept coming throughout this period. Reality doesn’t support this view, as the following figures show.
Proven oil reserves in 2002 amounted to 1,190.70 bn barrels. Five years later, in 2007, world oil reserves stood at 1,253.00 bn barrels. This is an increase in reserves of 5.23%. So while crude oil prices skyrocketed by 176%, reserves only increased by a meager 5.23%. Either no one wanted to find more oil, or there isn’t anything left to find.
The next table gives us a clearer picture of the regions and their respective reserves in bn barrels over this period.

Two regions (Europe and Asia Pacific) actually reduced their reserves, two regions (Middle East and North America) slightly increased reserves, and only two regions showed real growth rates, namely Africa and South & Central America.
Once again, it is revealing to dig deeper.
