re: Astrophysicist Dr. Willie Soon explains the abiotic origins of hydrocarbons.

Not in a position to watch/listen, so apologies if this is covered in the video, but something I only learned a few years ago:
The "fossil" in "fossil fuel" means that it can be found by digging in the earth, and that usage predates our modern usage of "fossil" by a couple hundred years.

This will probably be a stupid comment, but how can it be fossils if you are going several miles plus deep into the earth to get it. Where did all the sediment and rock come from

Right. It just suggest that the physical process is possible.
If the abiotic creation of hydrocarbons is being created 50 miles below our feet, 1.) we cannot physically witness it and to 2.) we do not have the materials to physically duplicate the process. The pressures and temperatures are too high.

By "our" I assume you mean earth.

River basins are a main source of sediment deposition

Yes.
But perhaps elsewhere as well.

Thanks for the education on this. I do have a question. My understanding is that the "crude oil" sent to refineries has different grades. For instance I remember a while back that when the gulf refineries stopped getting a higher or sweeter grade crude, from Venezuela I think, that things didn't go as smooth. So my question: is the grade of crude based upon the type of decaying organism or unrelated and due to other sediments entirely?

Why is this important? Or rather, describe for me the process at the molecular level. How can we make the distinction between abiotic versus biotic origins? What would we look for as byproducts?

sour vs sweet has to do with sulfur content

The grade of crude is based on its API number. A high API crude is thin and flows well. A low API is thick and can be thick as tar.
Whether a crude is sweet or sour depends on it's sulfur content. Generally 0.5% sulfur or above is considered sour. It really depends on whether or not a refinery can process the sulfur containing crude or not.

There is plenty in the fossil record prior to the Cambrian explosion.

Valid questions I do not have an answer to.
But I would start with a nuclear process rather than a chemical process to form elemental carbon and hydrogen to form hydrocarbons, (the simplest being methane).
...I just googled it and Sabatier chemical reaction is abiotic:
CO2 + 4H2 -----> CH4 + 2H20
Takes 400 degrees C and about 450 psig.

It’s worth discussion but carbon (hydrocarbons) are present throughout the universe. It doesn’t mean that it has to come from an organic source like dinosaurs and plants. I mean how did the dinosaurs and plants get it to begin with?
We are all small parts of the universe. The matter that we are made of will eventually return there.

So you're telling me there's such a thing as space dinos?
