Interesting book, but it has several flaws. First, why bother with all that geophysical stuff when nobody not in the field already is going to understand it and those in the field already know all that stuff? Seemed kinda pointless to me. Second, there's not that much factual evidence behind any of the stuff he talks about. Middle East is not producing oil anywhere near the capacity they could, and it is entirely unclear just how much oil reserves they have left. So, it would seem to me that the most probable situation is not a rapid decline in oil production in the next few year, but rather a hovering around the current production for some time before the decline starts.
