Oil is more Nick's field, but your info is correct: it wasn't mega-life; it was the the little critters that formed the organics that formed the shales that got cooked that bled kerogen that followed the faults that got caught in the anticlines...

I've followed the abiotic oil story for many years now, and it keeps failing to live up to the hype. a decade ago drilling was going on in a meteor crater, the idea being that the fracture system would have methane. That quietly went away after the dry, and very expensive, holes. Now it's Siberia, and if it weren't so darn cold, they could prove this theory.

It's true, there are abiotic hydrocarbons. But I've seen nothing to convince me that the big petroleum deposits came from anything but ooze, heat, pressure, a conduit and a trap. And I've a hard time buying the hype that abiotic oil will change the simple fact that the area under the petroleum discovery curve is greater than the area under the production curve. Discover this abiotic oil in fields to rival the Arabian deposits and then we can talk about putting off Peak Oil.

Otherwise, we've just about used up half of the oil we have discovered.

(as far as the electrical theory...naw. It's the structure related to salt domes that make for good oil traps.)
