Sure, Matt. It's a good question. We typically design these pads for more wells than we actually drill, the first pass-through. We will typically drill anywhere from 2 up to 6 wells per pad in today's world. That's trying to optimize our capital efficiency and that we get economies of scales, the more wells we put on a pad. But yet we're still trying to build infrastructure and delineate all of those different issues by stepping out as much as we can and doing that. As we go back, we have the ability to put a whole lot of wells on there. And I don't know if we could quote a number today because we've had various evolutions of designs as we go forward. But I think there will be a point in time where you could have 20, 30, 40 wells on a pad. There's no question about that. The real technology breakthrough that we need going forward is the ability to do multiple laterals out of a single wellbore. That technology does exist today, but it's extremely expensive. It's just simply cheaper to start over and drill a new grassroots vertical for each well today. But I think there's no doubt that, that's coming down the road. And what the good news is, in our overall long-term design -- and again, I can't stress this enough. We look at this project, really, for a long, long term going forward, 10, 15, 20 years out, because we think we have the resource potential as we've continued to demonstrate with gas in place maps. We keep rolling out more information as we gain confidence in history and have become very confident of what we're putting out there, that we can actually grow this for many years. So that's in all of our plans for midstream infrastructure, whether it's compressors, whether it's processing plants, how we power those compressor stations and processing plants. We're looking at how we would stack wells together, how we would handle condensate on these well site facilities. All of that's going into that plan. So to answer your question, although I can't give you a black-and-white answer, is it's a lot of wells.

And a second follow-up question, just in regards to your Permian drilling program, could you give us a little bit of color on, I guess, just around the acreage that you have in kind of the southern Glasscock area. And then as you guys mentioned, kind of the step-out Wolfberry test, I wanted to know kind of the implication on the number of locations. I think you guys mentioned up to 1,000 locations on 20-acre spacing, and how you may be able to accelerate development if that's kind of successful with incremental delineation here?
