Also, when we were in Alberta speaking with industry representatives, the statistics kept cropping that 80% of oil sands development is through in situ, and when we look at in situ, 95% of the water used for in situ production is recycled. Therefore, the implication is that as we move more towards in situ, the issue of water consumption goes away or is diminished.
Perhaps you could give us your take on the impact of in situ on aquifers, and the knowledge gaps that exist in terms of that.
