Thank you, Mr. Chairman.
I'd like to follow up on Mr. Allen's question concerning the size of the oil sands deposits and the reserves we've talked about.
If you take a look at the 140,000 square kilometres they've got, the total reserve in place, as estimated by the Alberta Energy and Utilities Board, is about 1.6 trillion barrels. If you could recover everything out of that area, that's what you would get.
Coming down from that, there is a question of what is ultimately recoverable. There are estimates based on the application of the technologies, the accessibility of the technologies, given the structure applicable to those sites, and that comes down to about 315 billion barrels. The 174 billion or 175 billion that was referred to by Mr. Brown is really the reserves that can be accessed right now with available technologies and the economics.
When we talk about the size of the reserves for the oil sands, we're talking about the most conservative estimate. There is a very strong possibility that you'll be able to access and produce substantially more than the 174 billion we've referred to. The Alberta government and the Alberta Energy and Utilities Board are really looking more towards the 315 billion barrel level.
