Yes. Well, look, one of them was that rig decision, and there's no doubt the rig market is increasing. And what I don't, it's hard to tell where the deepwater flow rig markets going to be just, picking a time, so they call the second half of 2023. And then what would that market look like? And so, we had an opportunity. And we know we want to engage, like I mentioned in the previous question, in two to three of these projects a year where we're operating a subsea tie back. And so the idea of getting this rig and just extending it, it doesn't add capital necessarily in 2022, as much as it would be in 2023. But capturing that now is it some measure away to kind of manage inflation in that marketplace, but we're seeing it everywhere you're seeing it on labor, when you have, you have to think about our operations, maybe a little differently than some of the onshore names you've, you follow? We use a lot of boats. We use a lot of helicopters, a lot of fuel involved, that's an operating cost. When prices are high, that's high. Obviously, there's labor pressures, there supply chain issues, that if you want it on time, a little quicker, you might have to pay a little more. And so all that's in the system, I think, our team, look, we had a big, first quarter beat on OpEx, yes, Shane you might have some comments, we had a first quarter beat on OpEx. And it just speaks to the team's ability to try to manage through that. And so, Shane, any thoughts on your side?
