Mr. Knight answers the letter explaining Alberta using carbon Dioxide to recover oil from mature fields is the same as done in Weyburn Saskatchewan. Weyburn being run by Encana and they are developing the technology at depths of 1500 meters which is above the minimum requirements to keep the carbon dioxide critical (liquid).
Weyburn crude is actually thinned by the Carbon Dioxide making it easier to recover and process. The thinning is carbon dioxide absorbed into the oil, being returned to the surface.
It will be interesting to see if Mr. Knight is as forth coming when the testing is done as in how much of the carbon dioxide that is put down the hole is returned to the atmosphere dissolved in the oil.
Alberta's carbon cap and trade system is going to be for Alberta only, not trade outside the province. That means this Government can balance any number of books and ledgers with carbon credits. Along with payments in kind taken on royalty, it is turning into a system where Alberta will receive whatever the oil companies and the Conservatives feel is necessary to keep this province above destitution.
