The origin of oil: abiotic or biological?

[sen-no-sen]

Yep ... Wiki, some alternative sites, nothing very clear.

[Janic]

has anyone calculated the mass of animals it would take to produce all the oil we know of?

It is clear that it is complex and that therefore the certainties for one or the other, are certainly false and that both are real !!

Simple arguments are much more valid:

The solar system was formed with lots of all the elements, lots of H2, less of C and therefore lots of CH4 and other molecules with C and H too !!

So the earth has received it like the other planets and satellites !!
So the earth has had abiotic CH4 with certainty !!
Why do you want the earth to be totally lost all this CH4, especially that in the very hot depths, there are atoms of C and H which only ask to reform a little CH4 among other very varied molecules !!
So it is illogical to affirm that all the abiotic CH4 of the very real departure or formed spontaneously afterwards, could not disappear completely, on earth !!!
Abiotic CH4 is a very small portion of the earth, like the Earth's atmosphere, but nevertheless huge for us !! Biotic is the same !!

Refusing this elementary good sense is the same as those who refused a century ago, the drift of the continents, despite the concordant evidence highlighted by Wegener, geology, earthquakes, mountains, etc. !!!
It took them to discover the ocean ridges so that if forced, they accept the evidence !!

So abiotic methane exists and therefore in the hot depths of oil formed under pressure exists.
Considering that life over 3 billion years on earth, the abiotic and biotic are strongly mixed !!!

Finally, even as biotic, we have huge reserves of fossil fuels underground, with a minimum of 600 million years of multicellular life doing photosynthesis on earth renewing almost all the oxygen in our atmosphere in about 200000 years = 0,2 , XNUMX million years, and as many carbon residues that end up in different forms with a small non-zero proportion stored in the earth !!
The mass of carbon thus separated is enormous in 600 million years, in atoms of C 600 / 0,2 = 3000 times the number of molecules of O2 in our atmosphere !!!!
So even if there is one per thousand underground (figure almost impossible to measure exactly, but there is a little left!), We have biotic underground enough to burn 6 times the oxygen in our atmosphere !!
So peak oil or fossil fuels is an illusion, just with the biotic and even more with the abiotic !!

This type of simple argument is enough to become aware of the fragile balance of life on earth which removes almost all the CO2 from our atmosphere, like that released by volcanoes, to store it especially in carbonates and in little combustible C !!

Life took 3 billion years to oxidize all the iron on its surface, before we could exist by breathing oxygen, finally free to exist, 600 million years ago !!

We can refuse the consistent indications but it is to refuse common sense most likely !!

has anyone calculated the mass of animals it would take to produce all the oil we know of?

Carbon chains and oxygen are mainly released by photosynthetic bacteria and plants, on which animals feed and therefore the carbon mass is above all that of these bacteria and plants (like peat and debris fallen to the bottom of the sea), which is measurable by the annual oscillations of atmospheric CO2 between summer and winter.
Most of it is recycled by life.
http://en.wikipedia.org/wiki/Gaia_Hypothesis
which is a certainty more than a hypothesis with disasters of imbalance sometimes before changing pseudo balance !!

But dedelco, we don't care about your two-ball analysis.

If there is abiotic oil, its only interest is to exploit it.
However, it is not the case.

There is no oil company that says that, apart from some enlightened Russians.
Companies search for petroleum based on theories of theories that work, and they do find it in sedimentary basins.

When the enlightened Russians find it in non-sedimentary basins, we will talk about it again.

And for info the International Energy Agency has officially declared the peak of oil Conventional in 2006.

microorganisms is more suitable than "animals".

[dedeleco]

Always contemptuous of lessdewatt with these peremptory certainties:

But dedelco, we don't care about your two-ball analysis.

We don't see them written anywhere !!
and I'm talking about any fossil fuel that can synthesize petroleum if desired!

Oil is mainly looking for reservoirs that have stored it more than the real source before migration, beautiful waterproof sedimentary pockets !!!

The peak is above all a means of raising prices with disaster capitalism, which sidelines sources as well, Iraq !!!

It is certain that we have underground enough to multiply the CO10 by 2, it happened 56 million years ago and even enough to burn all the oxygen as indicated with my orders of basic simple quantities, little indicated !!
And the fossil fuel peak is just a deceptive appearance, proven by my simple "two-bullet" order of magnitude arguments !! more accurate than pages and pages of detailed studies that get lost in complexity by forgetting the common sense of orders of magnitude never said !!!

[dedeleco]

And for info the International Energy Agency officially declared the peak of conventional oil in 2006.

as valid as the nuclear agency and the health agency which praises infallible nuclear power and which kills no one in disasters !!

In any case this peak does not frighten anyone, we continue to waste, to refuse summer solar energy for the winter, and oil and gas remain much cheaper at home, than the peak of local taxes which explode much more fast (3 times my heating not a wonder of savings without free wood) !!

[moinsdewatt]

Again, certainties that should look at the objective facts to allow very strong doubts !!

Where does the methane from, especially at very great depths, which are very real and not theoretical ????

We told you, microbial action. Nothing to do with abiotic gas.
Go see elsewhere than Wikipedia, this is also what is said by scientists.

Their quantity is enormous, even if difficult to recover and very dangerous, if we warm the ocean floor a little, as 56 million years ago, CO2 multiplied by 10 and much hotter !!!

Yes, the amount of clathrates (not chlatarates, ) at the bottom of the sea is colossal.
Besides, it 's starting to interest Japanese scientists. [/ Quote]

which is what speaks of "peremptory certainties" ??
We don't care about non-recoverable carbon.

Ha ha, Mr Dedelco alone against the world oil companies.

There are really fun characters on this forum.

[dedeleco]

With CH4 in huge quantities, or coal, what can we do ???
Oil without great fundamental chemical difficulty since the 1930s !!!

So peak oil is a real illusion as long as there are fossil fuels available, coal, methane, etc.

I do not like fashions and dogmas to deceive us !!

Ha ha, Mr Dedelco all alone against the world oil companies.
We told you, microbial action. Nothing to do with abiotic gas.
Go see elsewhere than Wikipedia, this is also what is said by scientists.

A century ago, the scientists in power refused the continental drift until the 1960s !!
The courts didn't talk about it at all, not proven, heretical !!

There are plenty of well-paid scientists to tell us bad guys: asbestos, pesticides, herbicides and GMOs, junk food, dyes, bisphenol A, Mediator and safe drugs, foolproof nuclear, etc.

I invite you to judge yourself with good sense, even the hyper-complex, with orders of magnitude often forgotten, losing people in precise details unnecessarily !!!
We never learn that at school in France, we want certain precision, only proven, more false than the vague in order of magnitude !!

The absence of an abiotic for CH4 is far from certain for simple reasons, the main thing is that the solar system is stuffed with it.
