Yes. I mean, again, everything is relative to the U.S. Energy platform. So a lot of the -- I would say, the small-cap-focused type of asset sales, whether that's M&A or usually more of an asset acquisition level in our core areas at the size of deals that we look at, right? Like a lot of those have to be evaluated for ARO environmental concerns, a lot more goes into it now. I know you know this than it did in the past. So whenever we see packages, a lot of these packages I mean commodity prices being strong have helped.
But a lot of them once you bake in the mandatory P&A and the mandatory ARO assumptions, a lot of these assets are really liabilities. And even the ones that aren't. Again, I'm not talking about the cream of the crop Delaware Basin, Midland Basin type of assets. But everywhere else carries a pretty big P&A ARO liability.
So as we look at adding incremental barrels, if you will, in this market, we don't see at least, very rarely do we see opportunities that are lower risk, easier achievable and higher rates of return than what we already have in our existing portfolio, right?
The challenge there is we have a very large asset base that ranges from almost Canada to the southern border. And it's finding the right candidates to go in and spend the resources, spend the work. I think you've seen in a lot of these unconventional basins, again, across the [ Lower 48 ], a lot of recompletion refrac work go on. That's what we're looking at. A lot of our East Texas and Mid-Con stuff, we think that there are multiple at a minimum candidates that we have in the portfolio that could reasonably be looked at as high-value refrac candidates.
We executed on one on our East Texas property in the fourth quarter. It's early, so we don't have announceable results yet, but we're encouraged by the results that we've seen so far, and we're going to do more. So as you think about U.S. energy, we're always looking for the larger projects, always looking for initiatives that we'll be able to take and we'll be able to scale.
But in between those things, bringing on barrels from our existing portfolio is extremely attractive in the interim.
