I’m sure this question has been asked before but I was reading an article in Wired today that showed a graph of where the worlds oil reserves are and it struck me as odd that 57% of the known oil reserves are in such a small area of the world. Why is that? The world is a huge place after all and it seems that oil should be more evenly distributed instead of seemingly concentrated in a relatively small area. Whats special about the Middle East region that makes it have such an abundance of oil while other places don’t seem to have any at all? Is it just that the oil is easier to get at or is it something else?
