This does an okay job in explaining EROEI

Though, the site still looks like its under construction. But here is a list

An article on Wikipedia states
when oil was originally discovered, it took on average one barrel of oil to find, extract, and process about 100 barrels of oil. That ratio has declined steadily over the last century to about 3 in the US (and about 10 in Saudi Arabia).

So, yes. On average, for every three barrels we grab we spend the equivelant of one, within the US anyway.
Can't seem to find a historical charts on EROEI but I did find some historical prices. 1997 oil was under $5 a barrel. Natural Gas was a little over $2.

So what's that a 1200% increase in the price of oil and a 700% increase in price of Natural Gas?
Is it just the commodity traders have a field day or is the stuff coming out slower?
