And so their opinion seems to be that the oil peak will not be a concern until 2020,

What I don't get is that even if you believe this date, it's still terrifying. That's only 14 years away! Blink of an eye.

CERA's detailed analysis only takes it to 2015, so I don't know how they claim no peak until the 3rd or 4th decade of this century, followed by an undulating plateau for decades more. Does CERA have access to some time corridor that gives them this certainty? They claim that there could be as much capacity as 101 mbpd by 2010. So at least we should see if their analysis is on target within the next 4 years.
