Oil will not just "run out" because all oil production follows a bell curve. This is true whether we're talking about an individual field, a country, or on the planet as a whole.

Oil is increasingly plentiful on the upslope of the bell curve, increasingly scarce and expensive on the down slope. The peak of the curve coincides with the point at which the endowment of oil has been 50 percent depleted. Once the peak is passed, oil production begins to go down while cost begins to go up.

In practical and considerably oversimplified terms, this means that if 2005 was the year of global Peak Oil, worldwide oil production in the year 2030 will be the same as it was in 1980. However, the world’s population in 2030 will be both much larger (approximately twice) and much more industrialized (oil-dependent) than it was in 1980. Consequently, worldwide demand for oil will outpace worldwide production of oil by a significant margin. As a result, the price will skyrocket, oil dependant economies will crumble, and resource wars will explode.

The effects of even a small drop in production can be devastating. For instance, during the 1970s oil shocks, shortfalls in production as small as 5% caused the price of oil to nearly quadruple. The same thing happened in California a few years ago with natural gas: a production drop of less than 5% caused prices to skyrocket by 400%.

The coming oil shocks won't be so short lived. They represent the onset of a new, permanent condition. Once the decline gets under way, production will drop (conservatively) by 3% per year, every year. War, terrorism, extreme weather and other "above ground" geopolitical factors will likely push the effective decline rate past 10% per year, thus cutting the total supply by 50% in 7 years.

These estimate comes from numerous sources, not the least of which is Vice President Dick Cheney himself. In a 1999 speech he gave while still CEO of Halliburton, Cheney stated: By some estimates, there will be an average of two-percent annual growth in global oil demand over the years ahead, along with, conservatively, a three-percent natural decline in production from existing reserves. That means by 2010 we will need an additional 50 million barrels per day.

Cheney's assesement is supported by the estimates of numerous non-political, retired, and now disinterested scientists, many of whom believe global oil production will peak and go into terminal decline within the next five years, if it hasn't already. Many industry insiders think the decline rate will far higher than Cheney anticipated in 1999. Andrew Gould, CEO of the giant oil services firm Schlumberger, for instance, recently stated that "An accurate average decline rate of 8% is not an unreasonable assumption." Some industry analysts are anticipating decline rates as high as 13% per year. A 13% yearly decline rate would cause gobal production to drop by 75% in less than 11 years.

If a 5% drop in production caused prices to triple in the 1970s, what do you think a 50% or 75% drop is going to do?
