Gasoline primer

[xoxoxoBruce]

16% of our energy consumption, is in the form of gasoline, according to the primer.
Everything you ever were allowed to know about gasoline marketing and pricing.

Thanks for sharing Bruce...Jesus am I on the right board?

I'm mostly here to take pity on you with your post with 0 replies.

Everyone's gone for the big weekend, Blue. Its you and me kid.

We're a nation of gas guzzlers. Uhmmm... Love those fumes and those dotted yellow lines. Between the two of them, they'll always keep me flyin'.

[wolf]

That's what got you into trouble in the first place.

No fumes for you!

It's not a chat room, blue. People get to it when they can/wish. People that have lives and jobs that keep them off the PC, most of the time. LJ said something about keeping up a running string of posts so people have something to read every couple of hours, and not wander away. But people that can only get on the board once a day, or less, can't keep up with the threads and they'll be driven away. How many times have you seen someone post, "I've been away a week/few days and the whole place has changed/gone to hell." There's an awful lot of us that don't use a computer at work, or if we do, can't go net surfing. So, no need to feel sorry, if I find it interesting, I'll post it and people can take it or leave it in their own good time.

It was a joke Bruce.

[xoxoxoBruce]

Yes it was.

interesting article... thanks for posting it...

I am reading this book at the moment and although I know "the end of the world is coming" is something that a lot of people have been shouting for quite a while a lot of what the author write makes a lot of sense to me.
Basically the argument can be reduced to one that our economy requires growth, but how can growth continue infinitely in a finite world? Without cheap energy intensive fuel to power our economy it will collapse. Soon demand for oil will outstrip cheap supplies for it and the price of oil will head upward and will stay there (the Peak oil concept ).

I would be interested if anyone who disagrees with this author could recommend me a book from the other side of the argument as I have scared myself silly and could do with some calming down

Not that I necessarily agree with them, or disagree with your author, I haven't looked into it enough yet, but here you go.

Thanks for that troubleshooter, I had heard of the "hot deep" theory before.

I have downloaded Gold's 1992 paper and will study it at dept when I have time.

One thing strikes me is if oil is a renewable resource why did oil production in the US peak in 1970 and why has it not recovered yet?

perhaps it is possible that oil is a biotic product but the process of it's biotic creation is slow and reservoirs can be emptied and only refill in timescales that are of no use to Mankind

It could also be a function of market trends or possibly a policy designed to forcibly limit the market or a limitation of production capacity as opposed to available reserves.

An awful lot of the wells you see throughout the south and southwest, are the old pump type. The oil doesn't "gush" anymore and it's difficult/expensive to extract. Those wells are shut down unless the market price exceeds a threshhold that makes it economically viable to open them again.

I'll try to find an article on it but one of the theories to reinvigorate the wells is to start flooding them with saltwater and float the oil up as well as preventing underground pockets from forming.

Here is a comment made by a professional geologist on another site regarding the Gold theory:

"the fact remains that the abiotic theory of petroleum genesis has zero credibility for economically interesting accumulations. 99.9999% of the world's liquid hydrocarbons are produced by maturation of organic matter derived from organisms. To deny this means you have to come up with good explanations for the following observations.

1) The almost universal association of petroleum with sedimentary rocks.

2) The close link between petroleum reservoirs and source rocks as shown by biomarkers (the source rocks contain the same organic markers as the petroleum, essentially chemically fingerprinting the two).

3) The consistent variation of biomarkers in petroleum in accordance with the history of life on earth (biomarkers indicative of land plants are found only in Devonian and younger rocks, that formed by marine plankton only in Neoproterozoic and younger rocks, the oldest oils containing only biomarkers of bacteria).

3) The close link between the biomarkers in source rock and depositional environment (source rocks containing biomarkers of land plants are found only in terrestrial and shallow marine sediments, those indicating marine conditions only in marine sediments, those from hypersaline lakes containing only bacterial biomarkers).

4) Progressive destruction of oil when heated to over 100 degrees (precluding formation and/or migration at high temperatures as implied by the abiogenic postulate).

5) The generation of petroleum from kerogen on heating in the laboratory (complete with biomarkers), as suggested by the biogenic theory.

6) The strong enrichment in C12 of petroleum indicative of biological fractionation (no inorganic process can cause anything like the fractionation of light carbon that is seen in petroleum).

7) The location of petroleum reservoirs down the hydraulic gradient from the source rocks in many cases (those which are not are in areas where there is clear evidence of post migration tectonism).

8 ) The almost complete absence of significant petroleum occurrences in igneous and metamorphic rocks (the rare exceptions discussed below).

The evidence usually cited in favour of abiogenic petroleum can all be better explained by the biogenic hypothesis e.g.:

9) Rare traces of cooked pyrobitumens in igneous rocks (better explained by reaction with organic rich country rocks, with which the pyrobitumens can usually be tied).

10) Rare traces of cooked pyrobitumens in metamorphic rocks (better explained by metamorphism of residual hydrocarbons in the protolith).

11) The very rare occurrence of small hydrocarbon accumulations in igneous or metamorphic rocks (in every case these are adjacent to organic rich sedimentary rocks to which the hydrocarbons can be tied via biomarkers).

12) The presence of undoubted mantle derived gases (such as He and some CO2) in some natural gas (there is no reason why gas accumulations must be all from one source, given that some petroleum fields are of mixed provenance it is inevitable that some mantle gas contamination of biogenic hydrocarbons will occur under some circumstances).

13) The presence of traces of hydrocarbons in deep wells in crystalline rock (these can be formed by a range of processes, including metamorphic synthesis by the fischer-tropsch reaction, or from residual organic matter as in 10).

14) Traces of hydrocarbon gases in magma volatiles (in most cases magmas ascend through sedimentary succession, any organic matter present will be thermally cracked and some will be incorporated into the volatile phase, some fischer-tropsch synthesis can also occur).

15) Traces of hydrocarbon gases at mid ocean ridges (such traces are not surprising given that the upper mantle has been contaminated with biogenic organic matter through several billion years of subduction, the answer to 14 may be applicable also).

The geological evidence is utterly against the abiogenic postulate."
