Hydrocarbons In The Deep Earth?

I would have thought it was the other way...hmmm...thanks.

Same theories have been thrown around for many years. With of course two opposite opinions and number of in between to flavor the arguments.

So... the real question is how long does it take to turn algae into oil?

Temperature and Pressure would seem to be the most significant factors, and those would also seem to be almost unlimited.

For instance, many oil reservoirs are found under what is later to be determined as an ancient meteorite strike.

Something like that could create tremendous, and almost inconceivable pressures and temperatures.

"But I am guessing none of those moons are big enough to generate the pressures needed as illustrated by the Carnegie-Mellon experiment to produce methanes."

The host planets could cause massive pressures on their moons, depending on how close their orbits are to the planets. I'd say a planet the size of Jupiter or Saturn could do some amazing stuff to moons orbiting at the 'right' distance.

In refineries, we use heat and pressure to breakdown the longchain hydrocarbons found in heavy oil into smaller, more valuable products like octane and decane. The same process is going on underground, but more slowly without controls.

It starts with far larger molecules like protiens and complex carbohydrates.

A relatively short, simple summary on what and where oil is actually found, not a possibility based on theories.

Think Permian Extinction. Big impact events leading to crustal upheavals would bury a lot of things deep, possibly in magma.

The bottom line is, we simply don’t know anywhere near enough yet.

..if I remember correctly this idea was promoted heavily at the 1964 World Fair.

Could be a reason this one of many erroneous ideas still permeates common cultural consciousness.

Another way of asking the same question is how did that abiotic oil migrate into the very hard and tight bakken shale(mudstone).

It didn't migrate there, it was generated there in the organic rich upper and lower Bakken Shales and migrated into the porous limestone, dolomite, and sandstone in the Middle Bakken and upper Three Forks.

As they say, geology ain’t rocket science!

No, it's rock science (no E. T.).

I believe, regardless of the formation process, we are consuming it faster than it is produced. If not, I would not expect us to continue to need to go deeper to meet production demands.

That's an incoherent series of "I believes or not expects" based simply on the basis that the old theory is no longer tenable.
Without knowing the mechanism, no "using it faster than it can be produced" assertion is rational. After all, when oil was "discovered," it was bubbling out of the ground.

I could, for example, posit that plate tectonics brings it close to the surface all over the place. We just haven't unraveled the means of knowing where to drill.

All is speculation.

I find my Car runs better on Brontosaurus than on T Rex.

If you want better mileage, Velociraptor is the way to go.

You replied to the wrong poster.
