I must respectfully disagree. The IEA wasn't a little wrong here, or a little wrong there, the solution to which is shaving a few percentage points off their numbers to make it agree with someone else. They were wrong down at the structural level, so the value of their projections and numbers are simply zero.
It's not that they were "a little wrong here, or a little wrong there," but as you put it, "[t]hey were wrong down at the structural level." That is why more than five years ago, it was argued that oil production would rise to around 115 mb/d by 2015 and oil prices would drop by less than $60 due to new oil discoveries, new technologie, etc. With less than three years left, and we're not even close to that. Three years ago, Saudi Arabia boasted that they would reach 15 mb/d by 2011. Now, they can barely reach 10 mb/d.
The "structural" problems involve ignorance of EROEI, historical flow rates, etc. If these "structural level" issues had been resolved, we would see lower estimates.
Thus, "the value of their projections and numbers are simply zero" because they are overestimated. But even those over-estimates cannot be hidden for long, as shown in one report from another released by various groups, including ironically oil companies.

With that, the oil industry had indeed been trying to "bury" the "idea of 'peak oil'" not by debunking it but by ignoring it, promising production ramp-ups and lower prices. But more reports from several of their companies reveal otherwise.
