With regard to Aventine, Aventine is multiple companies at that site. So Aventine is set up to support Greater New Mexico, all the way from Turkey Track and then our Greater Sand Dunes area. And so it's pumping service, it's oil country tubular goods, it's sand transload, sand delivery. It's a new sand last mile logistics system called SANDSTORM. It's the OxyChem ACL facility, and that's just where we're starting. With Schlumberger, it's frac, it's drilling tools, it's cementing, and it's providing logistics improvements by the location. In the Texas Delaware – so you treat each area based on what the current infrastructure is. In the Texas Delaware, it's really more about securing transload. And so we don't have the full scale buildout of an Aventine-like facility, but we have transload secured. It's closer to the regional sands in Texas. Our sand provider has a regional sand mine that will be opening shortly, and so we'll take advantage of that in the Texas Delaware. And in the Midland Basin, really, the infrastructure is pretty good; it's just really securing supply of sand. To give you just a couple of stats on the New Mexico impact, you think about the proximity of that to the well sites. It's a 60% reduction in the number of miles driven. You go from almost 20 million miles to 8 million miles. And then, when you put in the new SANDSTORM system that we're starting up this year, we can haul 27 tons of sand per load versus 22 tons. You do that math, that drives another 1.3 million miles out of the equation. So it's 33,000 fewer truckloads over a five-year period. It also reduces 9,000 metric tons of CO2. You think about accident statistics. It will improve our safety. And then, the new SANDSTORM system, that's really the last mile part of this, reduces the number of people required on-site, because of the automated nature of the way it works. So that SANDSTORM technology would apply both in New Mexico, Texas Delaware and Midland. And then, the logistics hub design and complexity varies as you move across those three areas as well.
