The WPX Mandan North Wells

July 16, 2021: from a reader after the data below was posted:

That WPX well #33382 was re-injecting a solid 100,000 cubic feet of gas per day ... undoubtedly for gas lift purposes.

From my readings, I suspect both Bakken and Eagle Ford operators are leading the way in forward-looking practices while the Permian players continue to struggle a bit. 

Reply: my hunch: in addition, I do think the operators in the Bakken know the geology like the "back of their hand" as they say.

Was there a parent Mandan well? Not really, but this one comes close. This one runs east to west, whereas the Mandan North wells run north to south, 

• 18986, PA/273, WPX, Mandan 13-14H, Reunion Bay, t10/11; cum 133K 9/17;

Production gives the lie to the meme that daughter wells perform substantially worse than parent wells. Initial production data:

33382, still producing nicely but, of course, has plateaued to a much lower monthly production rate:
