Why aren’t the oilsands companies planning on using CO2 for enhanced oil recovery?

In their press conference at the Lloydminster Heavy Oil Show on Sept. 11, Pipeline Online asked Saskatchewan Premier Scott Moe and Alberta Premier Danielle Smith about that. (For the record, CBC Alberta asked about hockey tickets for cabinet members and City News asked about a train line in Calgary, while at an oil show in Lloydminster. But at least City did ask about pipelines beforehand.)
