Now, looking just a little deeper, the Rhub al Khali (empty quarter) of Saudi is conservatively estimated to contain upwards of six-eight times the oil produced from the al Hassa basin since 1938
No chance of democracy in Saudia Arabia then, ever?
No really, broadly speaking I think 411A has it correct. Though I probably don't agree with his exact numbers. Thanks for that 411A. You've indirectly exposed the phony 'war on/of terror' for what it really is - a massive oil grab!
Now back on topic. If you look at the way the entire world including industry is planning for the future you can plainly see we are not a world that is planning around a scenario where we have no oil. In that is a message that supplies are not about to end anytime soon. Humans are crazy but not that crazy.
