I might add to that.
You were asking about the technical capability. CERI did a study about two or three years ago on the capability of the basin, working with the Alberta Geological Survey, SNC-Lavalin, and Adams Pearson Associates. They evaluated the capacity of the reservoirs in Alberta and western Canada to sequester carbon dioxide, and again for tertiary recovery, which my colleague has talked about. The technical capability of the reservoirs is very high. If you can get oil and gas out of these things, you can also put carbon dioxide into and take it out of these things as well.
So the technical capability is there, but as my colleague Bill Wall said, it comes down to the fact that there is a cost issue. How that can be done economically or commercially is another matter. But the technical capability to do it is there. The rocks will work.
