Again, we're going to give you a range--for example, Weyburn, in southern Saskatchewan, where you had a reservoir that was very receptive, with a relatively cheap and available source of carbon dioxide, is at the bottom end of the range.
If you are looking at large-scale capture and storage, I think the number that industry is talking about is in the $50-plus range for pure storage, with no enhanced oil recovery. There are a bunch of studies on that. If you want, we can make those available as well.
