I can appreciate what you are saying Joe. I haven't read about the origin of petroleum since Graduate school but there has never been a clear consensus as to where it comes from. The misnomer, fossil fuel, applies to it, natural gas and coal but to my knowledge coal is the only one that has direct ties to an organic origin. That aside and being that I am not a geochemist and have no idea what fractional distillation of hydrocarbons might do to the carbon. I resign and will accept what you say.
