Haven't missed it at all. It didn't stop the US from peaking again after the first or second times, or the world from repeaking again after the 1979 peak. It obviously matters, but depletion is just a measure of what the next round of change in incremental recovery factor looks like, or the next dive into the resource pyramid.
How much of the Orinoco extra heavy as been depleted? Next to none. Hydrates? 0. US oil shales? 0. Canadian tar sands? A very small percentage. The USGS put some tens of billions of barrels of reserve growth (incremental change in recovery factor to the rescue!) on the North Slope, Prudhoe being about the only field that has suffered any significant depletion, the Lisburne pool is still sitting there, just waiting. So no, haven't forgotten about depletion, just recognize that it has stopped Ohio from peaking like 3 different times now, the US at least twice, the world probably more than twice. So...someday it will matter, and in the meantime...how many more peak oils? The sine wave model rocks!
