Thank you.
I have a few more questions, Mr. Bruce. You talked about the difference between in situ and open pit.
On page 2 of the report that you referred to today, it says that typically, 2.0 to 4.5 cubic metres of water are required to produce 1 cubic metre of synthetic crude oil. Two paragraphs below, you're saying that it's 0.2--so two-tenths of a cubic metre to produce the bitumen using in situ. But then on page 5, you've used that same 0.2 cubic metres per metre of bitumen produced, and then you go on to say, “the demand for groundwater for in situ production could be as great as or greater than the demand for surface water for oil-sands mining”.
It seems to be a contradiction. On one hand you're saying it's less for in situ, and now you're saying it could be more.
