Thanks, Doug. This is Richard. I'll try to answer that and kind of start, like you said, with the well performance and then translate that into the inventory, which we wanted to bring back up. I think in total, this year has been a good year. I think we noted in prepared remarks, the growth trajectory of near 100,000 barrels a day from Q1 to Q4 and certainly, the second half of this year has been pronounced. But the best part of that has been the well performance.
And so both from a total year basis, that represents 200 wells in the Delaware that's really been drilled across our acreage from North Loving up into New Mexico into the multiple development areas there. And then even the third quarter results that we showed, that was across, I think, around 45 wells across Southeast New Mexico and Loving.
And so I say that -- really to say that the consistency we do believe is becoming the new normal as we continue to improve. And I think the Python well is exciting to disclose, but it's really, what's interesting about that is that entire North Loving development area has been consistently good. And even that DSU, where we had that record well, it had offset wells that had been drilled in a similar formation. And so being able to come back where we can develop a DSU with offsets that are child wells, if you like, and be able to have this sort of record performance, I think, is a real testament to the way we do our sort of subsurface development.
From an inventory perspective, I mean, I think the slide speaks for itself, we've got a lot of inventory that we've accumulated across a good acreage position. The only thing I would add to that is, we continue to have strong, what we would consider, secondary bench. They're not really secondary, because some of these are performing as well as the primary.
So I'd point you to some Second Bone Spring in the Delaware Basin and then even the Barnett appraisal that we noted in the highlight. Both of those have moved themselves up to really top tier in our development plans. We have optionality in terms of when we develop that and co-develop it, but it's good to see those secondary benches add to that inventory.
