Thank you very much, Mr. Chair.
I'm actually going to take up the same topic, in essence.
Mr. Kaufman, I understand, of course, that most of your costs are proprietary, but I'm wondering, you're the only person at the table who didn't answer what the cost of carbon sequestration would be. We heard last week from the Pembina Institute that it would be around 70¢ to $1.20. In essence, it's a dollar range per barrel to sequester carbon.
But after doing some research, I also discovered that it seems to depend a lot on how much you sequester, how efficient it is, as Mr. Keith said, and other issues.
Quite frankly, we've heard evidence that oil sands cost recovery is about $25 to $30 per barrel, compared to the Saudis, whose cost is about $1.50 to $3 per barrel. I have heard and seen other things in my research that indicate carbon sequestration could actually cost about $8 to $10 a barrel.
I'm not asking for specific proprietary information, but I'd like a range. I'm sure you have 5 or 10 or 50 or 100 engineers who go through and cost this out. Could you give us a range as to what it would cost?
