It's definitely area-specific, but we're certainly investigating. It's not unique in any sense. For example, in the Dawson Creek area there's another large unconventional gas play called Montney. It's a very prolific play. We're currently looking at subsurface aquifers there as well, roughly in the same kind of depth. They are there. Western Canada is a sedimentary basin, and that does afford those saline opportunities.
There's a timing aspect to the whole thing as well. As you go in to prove up your natural gas play, you initially look at the use of fresh water or near-surface waters, but as you start to get more and more confident that there's long-term development there, at the same time you'll start to look for these alternative water sources. One of the areas we look at is the subsurface saline aquifers.
