In this case modesty would be helpful.
You don't have a clue what your talking about.
Oil source rock is marine shales.
Period.
The one or two quibbling exceptions are not worth worrying about.
The marine shales must be capped with an impermeable layer (like salts).
They need to be buried and squeezed at a defined pressure.
They need to be cooked at a defined temperature for a fixed length of time.
If the recipe isn't followed correctly you get coal or natural gas or bitumens.
Thousands upon thousands of earth scientists like sedimentary petrologists, geophysicists, historical geologists and the like spend years and years studying the minutue of the topic.
The nut-bar "deep oil, other sources" crowd that you have quoted in this thread have never been proven.
They have however been disproven countless times.
In fact I personally remember when some nutty folks tried to drill a deep well to prove the "deeper"source of the Fort MacMurray tar sands.
Cost millions and disproved their own wacky theories.
Just quoting some completely unsubstantiated and unproven theory is really not much
to flatter yourself about.
