A CLR Hawkinson Well With A 13-Fold Jump In Production -- November 16, 2019

The CLR Hawkinson wells in Oakdale oil field are featured often on the blog. I don't think I have covered this particular well in a stand-alone post recently.

The well:
  • 24224, 681, CLR, Hawkinson 5-22H, 33-025-01954; Oakdale, middle Bakken, 30 stages, 2.8 million lbs, t9/13; cum 411K 41/9; went offline 3/19; not recently fracked;
Recent production:

So, what's the deal. It took a bit of sleuthing, but here's the answer. The sister wells on this pad, #24223 and #24225 also showed a significant jump in production.

It was obvious a neighboring well (or wells) had been recently fracked. None of the other Hawkinson wells had been recently fracked, and none of the others to the east showed a jump in production.

However, there it was, right on cue, a CLR Carus well in the neighboring drilling unit to the west had been fracked in 4/19. So, halo phenomenon. Clear as drilling mud.

The Saudis have not commented on this phenomenon but it is real and does effect the EUR.
