Thank you, Mr. Chairman.
First of all, to Mr. Alvarez and Mr. Stringham, I want to thank you for this excellent simplified handout that you gave us. Coming from Prince George, I could tell you all about the lumber industry and pine beetles, but I have to admit, until today I didn't know a whole lot about the oil sands. This is vivid.
Mr. Stringham, you said that you can recover 30% of the oil product from the sands and the other 70% stays in the ground. I presume you're referring to this diagram in which you inject the steam down into the ground as opposed to the shovel-and-bucket method.
