Let me speak first. I know Rob will want to say something about what Shell and Albian have done, and I'm sure Mark will as well.
What we have done at Syncrude is really focus on the processes that we have internally. We've spent $50 million a year on R and D since the inception of our operation back in 1978. It was us who actually invented the hydrotransport technology, and we sold it to others. We sold it to Shell, we sold it to Suncor, we sold it to CNRL. We've put a lot of effort into R and D into those processes. We have energy-efficient furnaces now. We have cogeneration on all of our steam generation and our power generation, so we're looking at the most efficient ways we can, from an energy consumption point of view, make a barrel.
That's where we've had our focus as a company. Others have gone beyond that, and maybe I'll let them speak to that.
