That's a good question. I did want to comment right up front that long-term storage of CO2 is one of the tools available. We also have a good, healthy opportunity, and we do this significantly, to use CO2 to drive more oil production out of a certain oil place. I think both provide, or one provides certainly, an opportunity to get more value out of CO2 that's pumped underground. It's not insignificant in terms of a value opportunity for Canada and the industry.
I would have to come back to you with more specific answers around how we manage the quality of CO2 in terms of the storage parameters and the use parameters. I can certainly dig around and make sure that's available.
