Had an old boss, electrical engineer and geologist, knew the oilfield front and back and every thing in between, who was convinced both processes led to the formation of oil.
Probably the smartest man I knew in oilfield work.
We do know that abiogenic hydrocarbons do exist, detected in space all over the place and we of course know that biological based hydrocarbons do exist.
That's why I view abiogenic as a possibility, although some will argue against that point till they are *blue in the face*.
Happens in space and on the moons of certain planets, why not deep underground under extreme pressures and temperature here?
We dang sure don't know everything about what happens below ground, why not keep an open mind?
I ran into a few of those blue n facers....lol
thanks for sharing your read....!
