That's very good topic to bring up, in Q3 we did 53,000 barrels a day, last year Q4, 146,000 barrels a day. And in Q1 we’re already outpacing that, we hope to get to 20% of all of water. That's over 400,000 barrels a day. So we're very excited about that business. From a customer demand perspective, that business continues to accelerate, everyone is getting comfortable utilizing produced water, even versus a year ago in the completions process. So I think there is a large runway there. You talked about margins, there's two sides of that coin. And I think you expressed it in the end, the less capital we have to spend for growth on disposal or even maintenance on disposal on wells is beneficial to us. We already see some of that benefit with our ability to sell water off of our system, certainly in areas of our system that may be heavily subscribed. So it's a great benefit there. There is also an OpEx savings that goes along with that. On the revenue side, we continue to see the value increase as demand has increased. We look -- there is water out there, a year ago people were getting water away off their systems. We have never done that, but we saw $0.10 a barrel. We've done deals, I guess, in May we were selling for $0.40 a barrel. So we're seeing the increase in the value of our water really increase from the revenue side quickly and also volumetrically. So it is a future. Keep in mind, we see that as, obviously, an ESG benefit. It's also a good fit with our customers, because they get to promote their ESG and also because they care and taking the demand off the offer first, but it's also been generally accepted in the industry most importantly, and it is cheaper than fresh or brakeage water. So it's a win-win for all parties. We see that as part of our business as a piece of our business. NGLs core business is oncoming revenue barrels which we used to say for disposal, but really we're taking those barrels off the customers' hands, so they can produce oil. What we do with that water subsequent to that is changing, but our core business and the numbers that we quote like Mike did in his opening, that's based on oncoming full fee revenue barrels for what has traditionally been described as disposal. The recycle and reused barrels, those do come out at a less -- of lesser fee. So they're not quite as impactful incrementally to our bottom line, but they are nice to have.
