I was referring to the debunking of the abiotic oil theories, not debunking peak oil (which is statistically obvious in terms of production). Abiotic methane? Sure. It's the simplest hydrocarbon. Abiotic crude oil, as you note, is somewhat more complex and my quick glance at the search results indicated a general debunking amid a frenzy of wild speculation. I don't know enough to opine myself, but I figured you would at least be familiar with the theories and that it might be of interest.

Here's an example of the 'imaginative' material pumped out at the time of the BP spill:

I chuckled to myself earlier thinking that if we could drill deep enough to get at pools of abiotic oil we wouldn't need it because we could simply generate plenty of energy from the thermal differential.

Definitely - especially the part about it having 'debunked' ... Although it seems to have been debunked, you may enjoy an article or two about 'abiotic oil'.

The idea has been intriguing for years - and when I first heard the theory (over 30 years ago) ... I contemptuously dismissed it ... and then started reading more. Hereby added to my infoquest list ... again. Wasn't aware that it had been 'debunked'.
It is interesting to me how many people think that 'peak oil' has been definitively put into the trashbin - again, people with very limited understanding making those claims. It is far, far from having been 'debunked' ... in fact, it is being proven to be an accurate assessment of 'total production history' more every single day. Abiotic oil (and abiotic gas) don't debunk the scientific facts behind 'peak oil' - they just change the overall parameters ... unless, of course, recoverable abiotic production rates exceed total consumption rates. There is little doubt that 'abiotic natural gas' does in fact happen - emissions of methane with volcanics are rather significant - and those certainly are NOT 'biotic sources'. The 'oil' - a little more problematic. (Some would argue that methane from volcanoes is actually 'biotic' due to sediment subduction ... but there ARE legitimate chemical reactions that can produce methane in the mantle ... from carbon present in sediments, but not just recycling already existing hydrocarbons, ex. carbonate rocks being source of carbon.)

I was (am) very sorely tempted to correct one of the Wikipedia entries on Cesium - where the 'authors' claim that Ce137/134 can not, and do not occur in nature - and tout the existence of those two isotopes as being SOLELY due to man's intervention - going so far as to state that those two isotopes did not exist on the face of the earth for BILLIONS of years. Patently untrue, and easily proven to be false. Fission DOES occur naturally - all the time, everyplace, both geologically historically and ongoing. The 'authors' simply do NOT understand 'radioactivity' as well as they think they do.

Just sat for a moment - and let the 'urge to correct' pass me by ... kinda like taking a system dump. *s*

I even ran across the documented existence of a sustained 'nuclear fission reactor' that occurred naturally - although the conclusion is that such an event is 'no longer possible' ... in their opinion.
Fascinating, actually.
