I thought it was the biogenic theory that had no science behind it. Please give a source.

Simple googling would provide as much as I could and I'm not nearly expert enough to recommend one article over another. However, I believe it boils down to predicting oil reserves--something abiogenic has been unable to find.

I believe I initially gained this knowledge over on theoildrum.com, and those people know their oil.

Does anyone have some source for this? It interests me.
