It depends on how you define enhanced, but with just the CO2 flooding there, it's relatively small from that perspective. Right now, we see conventional oil and oil sands are about one to one, so one out of every two barrels comes from either side of that.
As we move forward with the growth in the oil sands, one out of every four or five barrels is conventional. The rest of them are oil sands. But as you get to that range in the future, a lot of that will be done through enhanced oil recovery technologies.
The challenge we have is that in the conventional oil industry, we're recovering about 27% to 30% of the oil out of the ground. The other seventy-some-odd percent stays in the ground, because we can't get it out of the ground with today's technologies. New technologies like carbon dioxide will enhance that, and if you can--okay, go ahead.
