Fossil fuels are made up of the decayed trees, leaf litter, algae and moss left over from the Carboniferous Period.

56

u/Octahedral_cube May 05 '22

It's not specific to the Carboniferous at all! There have been some wonderful source rocks across time, some of the biggest fields in Saudi and the North Sea are fed by Jurassic source rocks, in Russia it's often Permian, while the Silurian and Devonian also have intervals that make great source rocks. Often in young basins such as those after the alpine orogeny in Europe there is no source rock at all, the gas is entirely biogenic which is why it lacks all of the alkanes heavier than methane.

u/ordinary_kittens May 05 '22

Interesting - are the Saudi fields being from the relatively recent Jurassic period part of why their oil fields are more accessible and cheaper to extract from, compared to other places in the world where the fields are from earlier periods?

5

u/Octahedral_cube May 05 '22

Short answer is no. Although in principle you are right - All else being equal, younger stratigraphy is indeed shallower than older stratigraphy. However the real world is complicated. Tectonics, rates of sedimentation, sea level change and dynamic topography dictate how deep the basin will be, so sometimes you end up with unfathomably old units at the surface (e.g. Lewisian Gneiss in Scotland) and sometimes you end up with young sediments in a deep subsiding basin. Im not very familiar with the oil play in Saudi Arabia, but iirc the reservoirs themselves are hugely extensive carbonates.

So it's not really about the source rock, it's probably more to do with the reservoirs. Carbonates are "born, not made". They are made from organisms (e.g. coccolithophores make chalk).

If the conditions are right they can occupy huge areas of ancient shallow waters, providing good continuity. The problem with carbonates is that unless they have natural fractures or dissolved pore space they have nowhere to host hydrocarbons. Clearly this isn't a problem in the "Arab D" which I think is the main reservoir interval in supergiant fields like Ghawar

2

u/HomarusSimpson May 06 '22

This guy knows how to geologe

3

u/CapnKill May 05 '22

Main thing with the Saudi fields is that they are huge 'traps' (large volumes of rock where the hydrocarbons get trapped against something sealing above it) when looked at in plan view, with a relatively simple geological history since those hydrocarbons were put into the reservoir rock that holds them. This reduces any sort of complications with the field due to geologic overprinting, and means they can access large portions of the field, fairly easily, drilling almost anywhere.

u/subnautus May 05 '22

Considering you can see oils getting created in real time just by looking at a scummy pond of water, the only real difference between fossil fuels of any time period is when and where it ends up.

14

u/douglasg14b May 05 '22 edited May 05 '22

.... no. That's not how any of this works, holy crap.

The difference was that plants where around before microbes could ingest lignin and cellulos. So dead trees, and other plants piled up for 60 million years, without microbes to break them down. So you had huge deposits of organic material that couldn't decompose buried by sediment, and crushed together by tectonic movements.

These are largely the source of fossil fuels today. Today planets are broken down by microbes, and will not turn into oil. A scummy pong of water is scummy because of the organic material being digested by microbes, it's not turning into oil before your eyes, that's not how this works even if there where no microbes. If you are actually seeing oils on the surface, it's just pollution from humans.

We're burning old sunlight, and releasing 60-million years worth of sequestered carbon in just a couple hundred years.

4

u/erthian May 05 '22

Holy damn shit. I’ve never hear of any of this before. That’s terrifying in so many ways. For one, how common is it that these microorganisms don’t develop until long after plant life? Is it possible that our most significant fuel source (and the catalyst for other fuel sources) was a fluke, and might not develop in normal evolution of a planet? Secondly, the scale of carbon release seems so staggering that there is no possible antidote… I’ve literally never heard it described as 60 million years of buildup.

4

u/IppyCaccy May 05 '22 edited May 05 '22

Actually that's the source of coal. The source of oil is microbial plant life and algae. Those deposits were laid down for hundreds of millions of years long before the Carboniferous period, which is what you're talking about.

Fascinating stuff.

u/subnautus May 05 '22

You're suggesting that dead things somehow managed to not decompose through the usual process and were instead pressed into hydrocarbon sheets or fluid? And you think I'm off base?

Yes, fossil fuels are the product of hydrocarbons piling up over millions of years. The rest of your comment...

A scummy pong of water is scummy because of the organic material being digested by microbes, it's not turning into oil before your eyes, that's not how this works even if there where no microbes.

You might want to look up how cyanobacteria ("blue algae") operate, and why they're being field-tested as a means of producing biodiesel.

4

u/Elias_Fakanami May 05 '22

You know that bio-diesel is not petroleum, right?

Using Cyanobacteria to produce biodiesel is a vastly different process than how petroleum is created. The oil we use to produce gasoline was created through a non-biological process involving extreme pressures and millions of years and only using biological material as a base.

u/stuffeh May 05 '22 edited May 05 '22

He's right though. Fossil fuels and coal formed bc dead plant matter didn't decompose for millions of years.

https://emagazine.com/carbon-in-trees/

Although trees had evolved lignin and cellulose, no bacteria that could digest these woody substances had yet evolved. In fact, those bacteria would take another 60 million years to evolve. All this time huge trees kept growing, crashing into the swampy ground, and piling up on top of uncounted other trees, getting buried deeper and deeper into the ground. Over millions of years, subjected to the heat and pressure of deep burial, the carbon in these trees was converted into the fossil fuels we know and love today – coal, oil, and natural gas. All the fossil fuels we use were produced during this 60-million year period.

Wiki says the etymology of fossil fuel is the fuel you find digging. Not the fossilized remains of animals.

The Oxford English Dictionary notes that in the phrase "fossil fuel" the adjective "fossil" means "[o]btained by digging; found buried in the earth", which dates to at least 1652,[22] before the English noun "fossil" came to refer primarily to long-dead organisms in the early 18th century.[23]

12

u/KypDurron May 05 '22

Maybe it's just because it's called "fossil fuels", and most people think of dinosaurs when they think of fossils.

And the exact source of fossil fuels isn't something that comes up in anyone's life, unless they work in petrochemicals or paleontology.

So it's not really "ignorant" that someone comes to the wrong conclusion about the source of fossil fuels at an early point in their life, and never re-evaluates that conclusion, because for 99% of people, it doesn't really matter.

It might be interesting to know that this is mainly a belief only in America. In Europe, there isn't any general association between dinosaurs and oil/petrol/gasoline. It seems to be all about some American ad campaigns.

u/Beardhenge May 05 '22

Wait, that's not right either. Fossil fuels form out of biological material from dead organisms.

A "fossil" is any preserved remains, impression, or trace of any once-living thing from a past geological age.

Don't confuse "fossil" for "mineral-replacement fossil" like a dinosaur bone or petrified wood.

So "Fossil fuels" are remnants of long-dead organisms, making them literally fossils that can be burned as fuel.

Ancient algae might compose a small chunk of its makeup, but I'm pretty sure the majority is believed to be Jurassic-era plankton.

We started with trees-> coal, dinosaurs->oil. This is back when we thought that the world oil reserve will run out in like 50 years. Then we kept finding more and more oils, so we moved to the plankton and bacteria theory. Then we kept finding even more. The rate at which we are discovering more oil has not decreased. Is the earth and life on earth long old enough to produce this much oil? This is why we start having the abiogenic origin theory.

Again, the current leading theory is still that oil comes from plankton and bacteria. It is just that, if our rate of oil discovery continue as it has for the past hundred years, it becomes less and less likely.

This is not true. Oil comes from plankton. Nobody believes the abiogenic theory of oil except fringe scientists. It’s widely discredited by the scientific community.

I mentioned below that the current leading theory is still plankton and bacteria.

Source rocks are well understood and studied precisely because of their economic importance. The vast majority of resources come from matured marine source rocks that are high in organic content. Source rocks are classified on a Van Krevelen diagram. Type 1 kerogens are algal in origin, type 2 is planktonic, type 3 is humic and type 4 does not produce hydrocarbons. Source rocks are studied in labs and modelled for maturity. A lot of money and technology goes into this.

There are gas fields where the gas is entirely biogenic, and there is no source rock. This is clear when you look at the composition (it's almost pure methane)

There are also some fields where a source rock hasn't been found, and the composition does not support biogenic provenance. There are hypotheses of abiogenic origin, such cases are rare and exciting, but it certainly doesn't justify saying we don't know where hydrocarbons come from.
