Each system is different. In the SAGD process, we were talking about just using the straight steam. In the mining processes, they use electricity as well as hot water; they don't use as much steam. For the mining operations, one facility could be used for multiple facilities. You can transport hot water about 50 miles, whereas you can only transfer the steam about 15 miles.
