"Damn The Torpedoes, Full Speed Ahead" -- CLR's Bice / Dolezal -- May 24, 2021

The NDIC hearing dockets for June, 2021, were posted last week

Today, the NDIC announced three new cases (see link above).

Among the three additional cases, this:
  • 28847, CLR, sixteen wells on an existing 2560-acre unit; sections 29/32-146-95 and sections 5/8-145-95, Dunn County;

Note: if these wells are important to you, I recommend you go to the source for information / documentation. The notes below are for my benefit trying to understand the Bakken better. This is about as far as my headlights go so there may be content errors. As usual, there will always be typographical errors. 

 ***************************
The Wells

I only checked a few, but I believe CLR already has eight wells producing in this 2560-acre unit. If so, then case 28847 is for an additional eight wells. None of the existing wells are particularly good wells. It will be interesting if newer completions strategies change things.

  • 31509, running north, 306, CLR, Bice 6-32H1, Chimney Butte, t8/16; cum 112K 3/21; not a particularly good well; 30 stages; 9.5 million lbs sand; Three Forks, it looks like the vertical depth of the Three Forks first bench lateral was 10,970 feet. If these numbers are accurate, then the vertical separations was 80 feet and the horizontal separation at some points narrowed to zero feet -- in other words, the two pipes (#31509 and #17884) were "right on top of each other, but vertically separated by 80 feet;
  • 31510, running north, 760, CLR, Bice 5-32H, Chimney Butte, t8/16; cum 221K 3/21; 
  • 31511, running south, 439, CLR, Dolezal 5-5H, Chimney Butte, t1/18; cum 185K 3/21; 
  • 31512, running south, 307, CLR, Dolezal 6-5H1, Chimney Butte, t1/18; cum 185K 3/21;


  • 24835, running north, 1,473, CLR, Bice 3-32H, Chimney Butte, t12/13; cum 295K 3/21; 
  • 24836, running north, 416, CLR, Bice 4-32H1, Chimney Butte, t12/13; cum 211K 3/21; 
  • 24839, running south, 758, CLR, Dolezal 3-5H, Chimney Butte, t2/14; cum 290K 3/21; huge jump in production, 7/18; see #31511 and #31512 above; 
  • 24841, running south, 954, CLR, Dolezal 3-5H1, Chimney Butte, t2/14; cum 284K 3/21; no real jump in production when neighboring wells fracked;

Two parent wells sited in section 5:

  • 19728, running south, 549, CLR, Dolezal 2-5H, Chimney Butte, t5/11; cum 299K 3/21;
  • 17372, running south, 426, CLR, Dolezal 1-5H, Chimney Butte, t9/09; cum 203K 3/21; was off line as of 2/20; returned to production  3/21; a small jump in production in early 2014, but did not last long;

Two parent wells sited in section 29:

  • 17884, running south, 147, CLR, Bice 2-29H, Chimney Butte, t1/10; cum 442K 3/21; a small jump in production in early 2014, but did not last long;
  • 16943, running south, 516, CLR, Bice 1-29H, Chimney Butte, t5/08; cum 201K 3/21;
Note: it looks like the daughter wells are going to be better than the parent wells. Or at least, just as good. Just saying. Again, it will be interesting what the granddaughter wells will look like with new completion strategies.

Anti-Collision

17884, middle Bakken, 10,890' TVD. See #31509 above.

Note production for #17884 (reminder, the Three Forks first bench, #31509) with definite, but not huge, jump in production on/after/on/about 8/16), i.e., a halo effect between two differing formations. We talked about this a long, long time ago. If I recall correctly (and I probably don't), CLR used the Bice wells to show that the middle Bakken and the Three Forks first bench do not communicate.
