Skip to comments.Hydrocarbons Deep Within Earth: New Computational Study Reveals How
Posted on 04/18/2011 6:12:10 AM PDT by Red Badger
A new computational study published in the Proceedings of the National Academy of Sciences reveals how hydrocarbons may be formed from methane in deep Earth at extreme pressures and temperatures.
The thermodynamic and kinetic properties of hydrocarbons at high pressures and temperatures are important for understanding carbon reservoirs and fluxes in Earth.
The work provides a basis for understanding experiments that demonstrated polymerization of methane to form high hydrocarbons and earlier methane forming reactions under pressure.
Hydrocarbons (molecules composed of the elements hydrogen and carbon) are the main building block of crude oil and natural gas. Hydrocarbons contribute to the global carbon cycle (one of the most important cycles of Earth that allows for carbon to be recycled and reused throughout the biosphere and all of its organisms).
Geologists and geochemists believe that nearly all (more than 99 percent) of the hydrocarbons in commercially produced crude oil and natural gas are formed by the decomposition of the remains of living organisms, which were buried under layers of sediments in Earth's crust, a region approximately 5-10 miles below Earth's surface.

Oil is regenerating ping.............
But methane and hydrocarbons are responsible for global warming 5 miles under the earth.
been saying it for years...”peak oil” is a myth...
What we have is “restricted production”...
Fossils From Animals And Plants Are Not Necessary For Crude Oil And Natural Gas, Swedish Researchers Find
Discovery backs theory oil not ‘fossil fuel’
New evidence supports premise that Earth produces endless supply
40 to 95 miles deep, that is one heck of a long straw to get at it...
We were put here with God given talents on a planet with more resources than we can use in the time we have before the Revelation,
and of course, the left, under the direction of the “god of this age”, their ideological father, wants to restrict our usage of those God-given resources.
My guess is that we are currently using oil faster than the earth is producing it, but it does show that there is a lot more out there than previously thought and we should go use it. The more oil they find and the more we use, the more skeptical I am that it was formed only from decomposing animal matter. There is too much oil in too many different rock types and formations for that.
Coal, on the other hand, while also plentiful, is more than likely formed from decaying plant matter. It does have the fossils in it. Lots more plant matter than animal matter. Always has been.
And what about the methane lakes found on Saturn’s moon, Titan?
Considering we can make light, sweet crude from our own garbage, I would say that the idea that oil can only be made of decaying animals is a fantasy that should have been removed from the public idea 50 years ago.
You never heard of Titanic dinosaurs?
As long as living things continue to die. . . . . . . .
the abiotic process of oil confirmed once again. we just need to pump the existing out to order to give the new more room into which to rise.
I find it hard to believe that the (compacted, concentrated, partially converted to hydrocarbons) mass of dead plants and animals is greater than the amount of oil we have consumed to date.
I guess that it oozes to the top like a big zit..............
Igneous, metamorphic, and sedimentary.
If you find hydrocarbons located within the igneous rock, you can make the case for abiotic oil, but if you find the hydrocarbon trapped by the igneous rock, you can't make the case.
If you find hydrocarbons located within metamorphic and/or sedimentary rock, you made the case for an organic origin. If you find hydrocarbons trapped by metamorphic and/or sedimentary rock, you can't make the case for abiotic oil.
Nice mental image Red... :)
And there are more than a dozen different varieties of coal.
Oil is oil........
“I find it hard to believe that the (compacted, concentrated, partially converted to hydrocarbons) mass of dead plants and animals is greater than the amount of oil we have consumed to date.”
When I consider how old the earth is, however, I can believe it. Read “Annals of the Former World” by John McPhee, if you ever get the chance. Your head will spin when you start to think about how OLD the earth is. There was a lot of time for those plants to die and get dirt piled on them.
Wow. Abiogenic hydrocarbon formation. Amazing idea.
Oil is............. “Earth Juice”
Interesting. Possible new/more efficient catalysts for improving/replacing Fischer/Tropsch?? We've got lots of methane, but are short on octane and cetane (gasoline and diesel)
There’s heavy oil, light sweet oil, tar sands oil, three in one oil...
If crude oil is found outside a sediment I´d like to know about it.
MY personal favorite: Hawaiian Tropic Oil..................
That would be awesome.
If we can quickly, cheaply and efficiently convert methane to gasoline or diesel we would never run out of fuel...........

I'm sure you can find some in here..............
You mean Dmitri Mendeleev may have been right? But that would make him to be some kind of chemical genius or something.
But like B4Ranch above, I'm also following Rossi's "cold fusion" reactor with GREAT interest. Nothing about the way it has been handled indicates "scam" to me.
But how much is "a lot," really? It isn't just a factor of time, but of time under the correct conditions (which are rare). If the right conditions are not there 99.9% of the time, a billion years is shrunk to an effective million years, and probably less than that. It appears that for large stretches of time much of the earth has been under hostile conditions for large scale decomposition under great pressures. What percentage of the earth today (which is mature and therefore "ideal") exhibits these conditions? Not many acres.
The whole plosive "Billions and Billions," uttered in reverential and sacred tones, needs to be de-mystified. We should not be so quickly, almost religiously, enamored by "the Big Number." To put it in a little perspective, if the groundskeeper can't coax a billion blades of grass to show up on the White House lawn this year, it's going to look like real crap.
Periodically he was a genius............
>>Nothing about the way it has been handled indicates “scam” to me.<<
A couple of years ago I attempted to buy into his experiment but was turned down. Not because the amount I offered was too small but because he is determined to finance it himself. That’s what told me this man had a winner.
I’ve got a billion weeds in mine...............I know. I’ve pulled them all at least once...........
Mmmmmmmmm, juicy caboosies.
With my Geology degree in hand, I have a difficult time believing that crude is found outside of sediments.
The premise of this story is difficult for me to buy into;
What say you guys?
I agree with you.
But I get tired of discussing the point with people on Free Republic that don’t even understand what sedimentary rock is and how it is formed from the surface.
Also, in the refinery, we use heat and pressure to break down crude oil into simpler, smaller hydrocarbon molecules, not the reverse.
For any that think differently than that, they should try applying the math of our current consumption rate times a few hundred million years.
The volume would suggest if that was possible, the problem would not be finding oil, but how to keep from drowning in it.
Who’s to say that crude oil cannot be formed in several different ways.
There’s more than one way to skin a cat and make Chinese food.............
FWIW, I have less than no idea what I’m talking about :)
From what I’ve read, I understand that at one time there was actually very little oxygen roaming around the atmosphere, it was mostly CO2. As the plants got their foothold, the oxygen was freed, (kind of all at once, relatively speaking) to the extent that all of the iron in the oceans oxidized at once (relatively) giving us that band of red rock that can be found all over the earth. You can see it in Eastern Pennsylvania, where the very old mountains are showing us their roots. That had to be A LOT of plants to release that much oxygen.
And the conditions don’t have to be perfect all over the earth. Those perfect conditions move around the earth as the climate changes (and I don’t mean that in the evil climate change way!!).
To grab hold of these time periods, think about the Rocky Mountains, which are young, they were born 80-55 million years ago. The earth is 4.6 billion years old. (It helps me to refer to a billion as 1000 million....so the earth is 4600 million years old, and the rockies only 55 million.) (So I get really irritated at global warming people, ‘cause I want to know what the heck melted the glaciers 12 THOUSAND years ago.)
I’m babbling, I know I’m babbling. Just remember that the rain forests are happily decomposing, and an awful lot of the coal came from shallow seas filled with seaweed.
Oh, this is not to say I don’t believe that the earth could be cranking out oil all by itself. Enough pressure, and I’m guessing you could rearrange those carbon chains any darned way you want to!
Your mileage may vary! I do love this stuff, though!
The compacted matter is far greater than we have pumped out. We have plenty of oil and will for the foreseeable future.
We just need a Prez who will give the OK to drill. There is one on the horizon who will do so as she is very aware of the situation we are in with oil.
You have a geology degree? I’m so jealous!
Seeing is believing, and when the day comes that there is a clear instance of abiogenic crude oil (without migration from other sedimentary formations), I'll gladly study it and maybe even believe it--if the evidence indicates that is the case.
In the meantime 'recharging' oil wells may have been merely coned in by overproduction and recovered after twenty years or so of sitting stagnant, or be 'recharged' along migration pathways (usually faults) by a deeper sedimentary reservoir. (Why drill deeper if you are getting the oil anyway?)
And yes, I have a degree in Geology and I've been examining drilled samples and cores on wellsites for over 30 years.
