Hi, From http://www.abc.net.au/rn/scienceshow/stories/2011/3198227.htm#transcript
"Fatih Birol: No, what we have done is in the year 2008 we had a look at 800 oil fields on a field by field basis. It is the most detailed study ever carried out in the world, and we have seen that the decline rate, the decline in the existing fields, are very, very deep. And since four or five years we are underlining one message, namely the existing fields are declining so sharply that in order to stay where we are in terms of production levels, in the next 25 years we have to find and develop four new Saudi Arabias." 4 new Saudi Arabias in the next 25 years! Who are they kidding? They'd be very lucky to find 1! Regards, Robin van Spaandonk http://rvanspaa.freehostia.com/Project.html
