Thank you, Mr. Chair.
I want to thank our witnesses for being here today. I think we're getting some great information, and it has been an interesting study.
I want to come back to upgrading. Three of my colleagues have already talked about that a little bit.
Both Mr. Wamboldt and Dr. Gray, I'd like you to talk a little bit about the innovation in upgrading. You've mentioned the catalysts. What other innovations will we see in upgrading? We've heard lots about extraction, various changes in the extraction processes, but how do you see innovation impacting upgrading over the next 10 years if you say it takes eight years to bring something online? What changes do you see coming there?
I'm going to ask SDTC if they have some projects they are working on in that area as well.
Dr. Gray, maybe you want to start.
