Sure, there are complex hydrocarbons in the outer planets and on their moons...such as Triton and Titan and Europa etc. And methane is very common in all the outer planets too. But all the facts about oil point to biological origin. ALso what we know about oil is that when it is buried at great depth it turns into natural gas. All the deepest hydrocarbon deposits found are gas. So it can't be the case that his theory that it is emerging from the interior is correct. OK there could be some non-biological tars or oils somewhere on Earth it can't be ruled out, but it doesn't seem to have anything to do with the huge oil deposits we know about and exploit if they really do exist. As for methane, he might have a point. But even then upper level reservoirs might be fed from even deeper biotic origin reservoirs. In mountain building, biological material can get thrust very deep into the crust.
