A Closer Look At A String Of Kraken TFH Wells In The Sanish --June 3, 2020

Many years ago, Lynn Helms opined that all things being equal, Three Forks wells might be better than middle Bakken wells.

Up until now, 90% of the Sanish oil field wells were middle Bakken wells. New permits suggest operators are moving toward half-and-half: new permits in Tier 1 areas are half middle Bakken, and half Three Forks wells.

I don't believe I have ever posted a multi-well pad with all TFH wells. If not, here is the first example:

The wells:
  • 36757, 794, Kraken Arrow A 15-22 4TFH, 60 stages, 15.3 million lbs; Sanish, t12/19; cum 108K 4/20; 
  • 36756, 732, Kraken Ethan 15-22 3TFH, Sanish, t12/19; cum 82K 4/20;
  • 36755, 1,531, Kraken, Penny 15-22 2TFH, Sanish, t12/19; cum 97K 3420;
  • 36754, 1,322, Kraken, Candace 15-22 1TFH, Sanish, t12/19; cum 97K 4/20;

From the file report (#36767):
  • a ten-foot target between 20' and 30' below the top of the Three forks 
  • a "toe-down, three-string, double section lateral"
  • the build took a bit longer than usual due to a mud motor failure; no big deal;
  • the lateral portion: from the evening of October 4, 2019, to TD, early morning, just after midnight, October 8, 2019, without incident (about 3.5 days)
  • gas: 
    • upper Bakken shale: 1842 units
    • middle Bakken: 413 units
    • lower Bakken: 2006 units
    • Three Forks: 1334 units
  • sections 15/22-154-92
From the NDIC map, the wells go to the south, intersecting the following, producing wells:
In same drilling unit:
  • 16953, Kraken, Fladeland, off line;
  • 22855, Kraken, Kathy, off line;
  • 21525, Kraken, Helen, off line;
