')1) The discovery trend claim is bogus because it does not include revisions over time of field size estimates.
2) Modern technology is not accelerating field declines through "super straw" technology and whatnot.
3) There is quite a bit more recoverable oil than the 2 triliion barrels claimed by peakers.
I'll just do a quick rebuttal here:
1. The discovery trend is very real. Giant fields are increasingly hard to find. Fewer large fields are discovered each decade. The data is very clear.
The revisions to field size are a red herring because the revisions typically do not substantially change the original discovery estimate. When they do, they often involve separate reservoir formations that technically are actually separate discoveries. For instance, the Prudhoe Bay oilfield here in Alaska has produced far more oil then was orginally cited at "discovery" but this is coming from new reservoir targets in the same stratigraphic pile.
2. Accelerating rates of field decline are occuring at Cantarell due to the modern gas injection technology used to drive production at the field. Its incontrovertible. The IEA has shown this is widespread phenomena, and its a reasonable assumption that similar rapid decines will occur at Ghawar when production peaks there.
3. Yes, of course there is more "oil" then the two trillion barrel estimate usually cited, but much of this is in tar sands and similar deposits that aren't conventional oil fields. The peak oil model doesn't deny that there are huge untapped aliquots of oil....it simply holds that the expense of recovering the oil from these unconventional sources will limit their exploitation to the point that they won't reverse the decline from peak production levels.

Excellent. That's what I'm talking about! Taking that cornie trash out in one shovelful.
