The original research that went into the oil sands was to develop the production of bitumen. The secondary development, which came about as a result of declining conventional oil, was the upgrading of bitumen to synthetic crude oil to promote the transportation of that product.
I don't think the idea of further upgrading of bitumen to refined petroleum products in Alberta has been totally discounted. All I said was that the economics of today probably don't support it, but these types of projects are 30- and 40-year manufacturing systems; eventually the economics will change, and that will probably change as the price of crude moves up. The business sector will come to the conclusion that investing in this industry will in fact make sense.
