>Oil doesn't extract and process itself, and there are many reserves of oil that will never make sense to pump. True, but the most desirable wells to oilmen once drilled do actually produce oil at such a high rate naturally without further energy input that they need to have their flow rate restricted in order to become manageable. Processing, maintenance and further drilling can then be accomplished from revenue itself without further capital investment. Relative to other things on Wall Street, it might as well extract and process itself.
