Export Land ModelThe Export Land Model, or Export-Land Model, refers to work done by Dallas geologist Jeffrey Brown, building on the work of others, and discussed widely on The Oil Drum. It models the decline in oil exports that result when an exporting nation experiences both a peak in oil production and an increase in domestic oil consumption. In such cases, exports decline at a far faster rate than the decline in oil production alone.
The Export Land Model is important to petroleum importing nations because when the rate of global petroleum production peaks and begins to decline, the petroleum available on the world market will decline much more steeply than the decline in total production.
This is a crucial piece of the Peak Oil puzzle, especially for the United States.
Jeff Brown and his mathematical sidekick "Khebab" have done a nice quantitative analysis of the prospects of the world's top 5 oil exporters
here. Their assessment is that the exports from these 5 will go to zero some time between 2025 and 2040. The current global recession/depression could push that date to the upper end of the range, but the USA should prepare for a world without an oil export market of any kind within 30 years. Of course, serious geopolitical consequences will kick in well before that time, especially if the new IEA decline projections are anywhere near accurate.
