It is also very obvious that overall production matches the rise and falls of OPEC oil production:

Only Africa and the Former Soviet Union have seen growth in recent years, and FSU production is now falttening out, as Russian oil companies brought back online the easiest fields after the crash of the early 90s; with the recently regained State control of the sector, investment to boost production does not appear to be the first priority.

Again, the picture is one where 'we', the 'West', appear to have little control over future supply, and are increasingly in competition with others who also need oil for their own growth/demand. Which points to only one thing: we need to reduce our demand, something we actually control, and that will actually have plenty of positive side effects (less pollution, more good jobs, less need to support dictators around the world and indirectly nurture gangsters with grievances, etc...)
