Certainly the idea of carbon capture and storage, along with the idea of enhanced oil recovery through carbon dioxide injection is being looked at quite seriously. I think there are five carbon dioxide EOR pilot projects under way right now. There is the operating Weyburn carbon dioxide project that has been in operation for two or three years in terms of carbon dioxide enhanced oil recovery.
Part of the problem is that the capture of carbon dioxide from smokestacks is relatively expensive, on the order of $60 per tonne. The folks who are doing the enhanced oil recovery can only afford to pay about $20 to $25 a tonne, so there's a bit of a disconnect there between the two sides.
Having said that, there are some projects by Penn West. They do plan to construct a small pipeline from, I think, Fort Saskatchewan to Pembina to undertake a carbon dioxide flood of the relatively mature Pembina field.
Beyond that, we recognize that there are some incentives or programs that are being sponsored by NRCan in terms of CCS.
