Proponents of abiotic petrogenesis, are you aware of any specific oil deposits that can be conclusively proven to have formed only by abiotic processes?
Being worried or thinking about something you'll never be able to control is not living. That's a miserable and slow death. (snip) It will be thousands of years though.
So why worry. Have fun.
Oligarchs living in Jabba the Hutt level wealth and luxury at the pinnacle of the petrodollar fuckpile are condemning millions of future humans to lives of poverty and misery by blocking conservation and replacement technologies to keep the petroleum gravy train running to the polluted bitter end.
You're bringing up a topic you have no control over. None.
Why bother spending millions influencing the 2nd poorest country in South America with no political influence to speak of, maintaining a huge mansion in the capital and lots of sponsorships to the tunes of millions USD/year?
If you're not personally benefiting at fuck-the-world levels of wealth, why are you so willing to pretend facts aren't so to only benefit oligarchs while harming your own self-interests?
The abiotic case is that carbonate rocks and water get subducted by plate tectonics and changed by the deep heat and pressure into petroleum spectrum molecules.
This is often brought up by people holding cornucopian pro-petroleum positions, suggesting that because it's an abiotic process, oil is endlessly renewable.
Proponents never take the hypothesis further and detail processes, timelines, and specific deposits showing clear evidence of abiotic origin. Furthermore, they never seem to recognize that even if petrogenesis proves 100% abiotic and as described, it's STILL too slow of a process to provide limitless energy resources to humans for limitless time.
The biotic case is that extant petroleum deposits consist of metamorphosed ancient biological deposits like algal mats in lakes. Much of the coal on earth was originally jungle land that existed before cellulose eating bacteria evolved, resulting in very long term in-situ accumulation of carbon.
Accessible oil shale deposits contain identifiable fossils and chemical signatures of biological processes. A particularly good example is the Messel Pit in Germany,
To start the discussion, let's first have an understanding on what "petroleum" is. "Petroleum" is a mixture of multiple types of hydrocarbon compounds
Actually, the petroleum industry was very much against the abiogenic theory.
A fundamental flaw in biogenic theory is chirality: complex organic molecules have left-handedness vs. right-handedness (isomers). Almost all biological organic molecules are left-handed (where chirality is possible for the chemical isomer),

That's why it is common to find oil at greater depth directly under coal mines, and natural gas (Methane) further down.
I'll tell you one weird thing about the Petroleum industry.
Exxon has an Ambassador in Paraguay, has for decades. But they claim there's no evidence of fossil fuels in the country.

You went to a lot of trouble to define petroleum in your first paragraph, then went on to mention carbon methane on non-Earth objects, but you didn't show petroleum elsewhere. Finding a Mars analogue of terrestrial petroleum deposits on the moon or mars would certainly shake up the notion of abiotic oil on earth... IF, IF it happens.
The industry is also simultaneously content for people TODAY to mass-believe in abiogenic oil as it plays to their advantage now. They need only passively STFU and let it propagate virally.
How would a theory that postulates practically unlimited supply of their primary product help them?
That more complex "petroleum" molecules form naturally ON EARTH from methane is not in dispute here.
What you HAVEN'T shown is a PROCESS where they have indisputably formed abiotically on earth. It doesn't MATTER to this question whether for instance polycyclic aromatic hydrocarbons are detectable in the Taurus Molecular Cloud, under the conditions that exist THERE.
What do you mean by "naturally"? Compressing Methane (CH4) alone wouldn't produce longer chains. It is microbial action stripping away hydrogen that concatenates CH4 into longer carbon chains
Besides, even on earth, it take years of surveying the grounds to find oil wells, we don't have nearly the technology to do that kind of in-depth survey on other planets or satellites.
@CaptainHorsePaste That's interesting. So what's the answer?
This branched out from the "origins of life" thread because the conversation pivoted to "abotic petroleum." Now you've taken it back full circle to the original M-U experiment where methane was one of the starting molecules shown capable of abiotically assembling into much more complex molecules.

IDK what your point, or your motivation to run the discussion all over the map like this is any more.

I already pointed out, spectrography has detected the signature of PAHs in other GALAXIES. This still doesn't prove they arose biotically, but certain other molecules might.
When you go into details you have to address another subject. What you'd need is a forum of discussion, and then breaking out threads for that.
Ethane is not at all a "much more complex molecule" than Methane.
Observing something in the space in a galaxy is quite different from finding oil well on a different planet.
We have known in the past couple decades that hydrocarbon exist in space in vast quantities. That has pretty much put an end to the biogenic theory of hydrocarbon for people who have really thought about the subject.
If people believe oil forms abiotically, and from there assume the process runs at least as fast as we are consuming said oil today, then it makes perfect sense to vote accordingly and let petroleum companies do as they please, pollution and conservation be damned and their proponents ruthlessly mocked and depreciated. This is as stupid as believing the claims of "fuel saver devices" that if true, installing 4 different kinds of them would make it necessary to stop every 50 miles to bail excess gas out of one's tank.
Well, we know rain replenish our water reservoir constantly, yet we do not waste water regardless whether we get water from the city/town or from private well.
Regardless where hydrocarbon originated, the effort refining it and bringing it to the gas station is not free of charge.
Think of "cost" in terms of energy. It you get 3 barrels of oil using the energy equivalent of 1 barrel of oil, is that "free"? Ignoring the cost of drilling, exploration, etc.
We KNOW methane forms abiotically and is common in the universe. We can detect much more complex hydrocarbon molecules in distant parts of the universe, and we HAVE. None of this proves whether the oil on Earth formed abiotically or not.
Only in people who have ulterior or surrogate motivations to believe in abiotic oil... and want a reason to never bother thinking about it again. That hydrocarbons have been detected in space is irrelevant to the question of whether Earth's petroleum bodies were formed biotically from ancient life, or abiotically by subduction of surface minerals in a continuing process.
One of the chief complaints about Canada's tar sands project isn't just the pipeline across US land, it's the fact that extracting it amounts to burning 20 to 30 gallons of methane natural gas in order to sell 1 gallon of gasoline.
When's the last time you watered your lawn?

With regard to abiotic oil in general though - Titan is covered with the stuff. It seems to form when the planet forms.

Very good point. that's why I mentioned the emerging technology of extracting carbon from sea water to form liquid fuel using solar energy will put a hard limit on how deep it is worth to drill for oil/gas.
Indeed. It is quite likely that the earth's surface was stripped of hydrocarbon by microbes eating the "easy food." After that, whenever pressure from below ruptures the surface (including sea floor), oil and gas rushes out or oozes out, and quickly eaten by microbes again. Before the mid-19th century, natural petroleum spill was a common local disaster for farmers. Eventually someone found use for it to save the whales from extinction.
You can just as easily burn coal to run a power plant, as you can burn methane, or gasoline, or anything.
If this is the case, it's really stupid, because it's easy to convert a vehicle to burn methane.
Ever heard of a thing called the Truth?
Another breakout discussion from a long thread. What are the origins of terrestrial petroleum deposits, biotic or abiotic?
From a Biblical perspective you are asking, did God create petroleum in the first seven days, or did it happen after that such as during the flood?
There is significant evidence that it happened as a result of geological processes consistent with catastrophic flood, huge breaks in the earth’s crust, perhaps even the breaking up of Pangea all at about the same time.

As opposed to a presupposition the likes of which you made numerous times in your argumentation? Yes.
They will all look basically the same with varying paint jobs.
One thing I've learned over my life is that although technology uses energy, the same device can both get better and use less energy
A car, for example, could take advantage of airflow to control it's direction with dynamic surfaces. Such a car would be entirely FUNCTIONAL, though. You'd end up with something akin to a bicycle which has been, basically perfected.

Let me be crystal clear on this: I am NOT asking from or for a BIBLICAL perspective. Good day.

Care to point out where?
Contrary to the narrative "The left's motivation isn't to prevent pollution, it's to take humanity back to the stone age before mechanized travel" is completely off base when you look at the evolution of the automobile from the 50s till today. What we GOT were cars that are extremely collision safe while becoming quite light, and economical and clean burning while performing well and being fun to drive.
It's amazing the incremental steps made to wring each additional sometimes 1/100th of a mile per gallon out of a car, like the time Volvo retooled their assembly plants to use fasteners one wrench size smaller therefore fractionally lighter throughout the car on a model that was ending production at the end of that year anyway, to meet that year's CAFE average. ICE Cars are a VERY mature technology, for the amount they can wring from a gallon of gas today.
Right after the part I quoted, you said "The biogenic theory was actually invented with ulterior motive: to make petroleum industry products sound more precious." This is not mutually agreed upon as fact, but what you wrote presupposes it's "the truth." Unironically, too.
And this: "That has pretty much put an end to the biogenic theory of hydrocarbon for people who have really thought about the subject." is a triple-nested cluster of presuppositions- that the biogenic theory is mutually considered ended, and that any people who think otherwise (IF these even exist) are people who have NOT really thought about the subject. I'd expect this level of subterfuge from someone else's dysfunctional Mother-in-law, perhaps, but not from partners in a discussion of scientific facts, theories, and hypotheses.

Accessible oil shale deposits contain identifiable fossils and chemical signatures of biological processes. A particularly good example is the Messel Pit in Germany, an ancient lake which formed in a deep volcanic vent with chronically low oxygen below the surface waters. The pit was believed to release intermittent clouds of CO2 that caused mass die-offs of larger animals, whose bodies sank to the hypoxic depths to become preserved in remarkably excellent condition. The contents of this pit were estimated to represent over a million years of accumulation, from a time period approximately 47 million years ago. Therefore, this pit is not only proof that oil CAN form biotically, it gives a lower bound of 47 million years needed for that to become oil under those specific conditions since. The location is believed over time to have drifted 10 degrees further North in latitude in addition to gaining up to a few hundred feet of overburden above the shale deposits. https://www.age-of-the-sage.org/evolution/messel_pit.html
