I can give you a little bit of a feel. I'll remind us of an experience that we had in, I believe it was mid-2014, when we started increasing the sand loads in our Delaware completions and we really ran up to – from about 600 pounds per lateral foot in early 2014 up to about 3,000 pounds per lateral foot through 2015. And, at the same time, that information gave us a good matrix or a good feel for the performance change in that design, but it also helped us understand the matrix associated with the commodity price environment. So we have backed off in the Delaware from that 3,000 pounds per lateral foot. We think we can get the most commercial returns in the current business environment done at about 1,500 to 2,000. It kind of varies across the field. So that's the way we think about it. And then if you move over into the Anadarko Basin, we're using a slick water job in our Woodford type work, and we continue to increase our proppant loads there. So we're up to about 2,000 pounds per lateral foot. And after drilling and completing over 800 wells, this last large pad that we brought on had the best results that we've ever had in the Cana-Woodford play. As we think about the STACK play right now, we're using a hybrid type job, so we've got a little bit of a gel with – the total fluid is more dominated with the slick water. So we're continuing to experiment and modify with our completion designs, but we are increasing our sand loads there up to about 2,600 to 2,750 pounds per lateral foot and enjoying increasing success there. So, John, we're getting a lot of this information, and we're really all about trying to make the highest return per well, not necessarily just to pump large jobs. So getting a lot of data out there, got a lot of data in our library and we pump a lot of slick water jobs. But in a few places like the Eagle Ford and in STACK right now, we're using a hybrid fluid.
