This may not be part of your briefing notes. In the intervening period, Shell has essentially backed away from the oil sands. It has reduced its contingent in Calgary with regard to heavy oil by approximately 90%. It's just maintaining its existing plants.
With regard to use of geothermal energy in the oil sands, it really was an inverted application, where it would be applied in a cooling function, to recapture the energy that comes up with the hot oil or hot bitumen in the separation phase. I don't think we've seen any material progress on that front.
