I'll answer only from the in situ standpoint here. Right now I believe we're making great strides in this. Roughly 95% of the water we use is recycled water. We don't take any water from open sources and none from the Athabasca River. We're using non-potable water; effectively it's not quite saline, but it's non-potable water.
So I really think that the technology we're using right now.... When I came over to this particular job from Australia, I was very impressed with the level of technology that's being used right now.
The next major step that we need to do, in my view, is getting that steam-oil ratio down, and we're looking at that by.... If you use less natural gas, you could have less steam, you could have fewer greenhouse emissions, and that's a real focus area for us, as well as the water usage.
