The notion of long chain hydrocarbons surviving cooking for millions of years is absurd regardless of pressure. There is no reversible chemistry involved where chain breaking is in equilibrium with chain re-forming. There is enough thermal energy available to break the chains into smaller and smaller units. These smaller pieces do not re-assemble since there is a high Gibbs' free energy barrier. Pressure does not stop this process since pressure is not chemistry and just keeps the stew in the pot.

The reason we can burn these long chain hydrocarbons is because their chains can be broken relatively easy and there is a net energy release in the process. Of course without an oxidant there is a Gibbs' free energy barrier but it is not high. If it was high, then the exothermic oxygen combustion chemistry would not apply.

This abiotic oil crankery can be debunked via a lab test where some petroleum is cooked under high pressure (we already have this in the form of thermal depolymerization). If this process had no net degradation effect, then we could cook oil from small chain hydrocarbons like CH4. In fact, it would be commercially viable.

Note how we get NADA from peakoilwhen re discussions of actual scientific test in a viable LAB to prove his theories? Only empty arm waving.

That says it all, no matter how much he flaps his arms, lips, and uses red font, etc.

I remember now why I gave up and put him on ignore long ago. I was hoping he had matured a bit and would at least deal a bit in facts. Nope. Well, back to ignoring his posts for a year or three, if he can't post actual content.

If he DOES post something meaningful, hopefully I'll see it in someone's quote.
Given the track record of the perma-doomer blogs, I wouldn't bet a fast crash doomer's money on their predictions.

For years and years in a row Saudi Arabia pumped huge amounts of oil and its reserves stayed the same. There is a whole thread about the possible (possibly never?) IPO that talks about the reserves being audited.

There are competing theories as to how Saudi Arabia could year after year replace exactly the amount of oil that was pumped.
Using Occam's razor [the problem-solving principle that the simplest solution tends to be the right one] the idea of abiotic oil seems a simple explanation for this :P
However, there could be an even simpler explanation "The figures were made up." :roll: 8O

as I have pointed out numerous times the problem people encounter when dealing with understanding this is the difference between various classes of reserves. The D&M analysis which is now available through the bond prospectus points out the number SA has been talking about all these years is Proven reserves. Throughout this whole time new wells are added, new techniques (MRC), new recovery factors (Ghawar recovery on average has increased from ~40% to ~72%) etc and that allows Reserves that were previously classified as Probable or Possible or even Contingent Resource to be elevated to the Proven category. BTW the audited reserves information is now publically available so you'll have to find some other conspiracy theory to latch onto other than "SA is lying about their reserves".

As to using Abiotic theory to explain Saudi Reserves or reserves anywhere else.....please give your head a shake. :roll:
