Actually, Brian and George have covered a couple of the bigger-picture questions I have. Maybe just a couple on specific assets. Are you able to provide any details, in terms of IP rates, on the 3 Duvernay wells that you have test results for?
Harold N. Kvisle - Chief Executive Officer, President, Independent Director, Chairman of Reserves Committee, Member of Executive Committee and Member of Human Resources Committee Well, we're not planning to provide any detail on that in a hurry. As usual, it'll all come out in due course. But at this time, we're planning our activities in the Duvernay, and we would not prematurely release that kind of information. Paul Smith may want to comment further on that. Paul?
Paul R. Smith - Executive Vice-President of North American Operations Yes. Mark, we said that we would -- I think get back to you once we drilled 6 wells, and we're 4 wells in, 3 completed in the north. We've -- actually, this week, we're completing our first well in the south. The rig is onto its second well in the south, and I think it's a very, very large area. We got 360,000 acres that span a very large part of the fairway, and I think it would be premature for us to sort of come out with individual well results. What I will say is that we continue to be encouraged by results that we're seeing, both our results and the results that you're seeing from the increasing industry activity both in the north, in particular, where the -- where industries are being focused up until now. But I think you're going to start to see a lot more activity in the south in the next 12 months, where we, and our competitors, are heading.
