It's about $13 today. Recently it was down to $9. So it fluctuates.
The principal reason for that differential is that there's a bottleneck in Cushing—from Cushing, for example, to the gulf coast. We can get lots of crude to Cushing, and then moving it beyond that there's a bit of a bottleneck. I'm just quoting what the industry says, but their view is that when you can de-bottleneck Cushing and get it past Cushing to, for example, the gulf coast refineries, you'll see these two prices come more into line. So to the extent that we do get oil to tidewater and it enters the international market, that's where the two price levels come more into line.
There was a recent study done by a university in Alberta—I think it was the University of Alberta—that basically underlined the fact that if you're selling your oil at somewhere like $13 a barrel less than what it's getting for Brent, and you multiply that by a couple of million dollars a day, it's a lot of money that you're leaving on the table. That's one of the reasons for the push to get Canadian oil to international markets.
I think our minister has been pretty clear on that. The U.S. is our best friend, our closest trading partner. We have great economic relations with the U.S., but strategically it would be wise of us as well to diversify beyond the U.S. market to make sure we're getting the best price possible for our crude.
