An interesting read regardless of your take on the oil situation. It seems there is a rather popular theory about the regenerative possibilities of oil. Instead of being a depletable fuel it could in fact be literally "primordial" in nature.
In the words of geologist Vladimir Porfir'yev, "The overwhelming preponderance of geological evidence compels the conclusion that crude oil and natural gas have no intrinsic connection with biological matter originating near the surface of the Earth. They are primordial materials which have erupted from great depths."
For more than 50 years, Russian and Ukrainian scientists have successfully used the abiotic theory to find oil and natural gas. For example, the Dnieper-Donets Basin has yielded a significant amount of oil and natural gas even though it is an area that conventional biological theories reject as unpromising. A recent technical paper found that the results "confirm the scientific conclusions that the oil and natural gas found in ... the Dnieper-Donets Basin are of deep, and abiotic, origin."
