Zeev, From what I hear it currently costs just under $10 US$ with royalties. The recent low in oil made some areas non-economic. I am not sure how they process it, I hear some is freed by steam heat, some by solvents and some by supercritical CO2. The CO2 method has the highest yield as it makes the lowest viscosity mixture with the oil, and it is easier to strip the CO2, but has the compression energy as a debit, but I understand they strip the CO2 in several passes at different pressures so that some CO2 does not need ambient to pressure energy. The grade varies from strata to strata, but in general it will be in large consistent stratas. I have seen shots of the draglines that strip the sand and send it to a processing area, like strip mining coal, but muckier. I have nbever worked there, but several projects were underway when I was at U of T. It was the holy grail of Canadian energy self sufficiency. How the psoraisis project going? Bill
