As we look at the opportunities for adding additional upgrading capacity, there are several of them that are planned, as you know. The North West upgrader is one. It was just announced in the last couple of weeks that it is moving ahead, and there are also expansions to existing facilities on the production side that have upgraders associated with them.
It is moving ahead, then, but it requires the synergy that we have seen happen down on the Gulf Coast. The efficiency here, I would say, is a combination of that upgrader with the upstream segment so that steam and electricity can be shared across or with the downstream refining segment, as we have in Fort Saskatchewan, or with the North West upgrader, whereby you can combine an upgrader with a refinery and then you're sharing the heat. You're not having the heat losses. You're sharing the utilities, and that's really where the efficiency gains can allow us to be competitive.
