Updates
December, 22, 2017: a reader noted I had the wrong production chart for one of the wells; that has been corrected. More important were his comments regarding these wells:
Original frac job required 660 days of production to produce 68,150 BBL of oil. In approximately 90 days (Aug, Sept, Oct) the well has produced 67,857.
FYI in November it produced 16,900 BBL. So in approx 126 days of production since refrac has produced 87,400. June-November.
Not bad for 4 months from a well that was put on production almost 9 years ago and had produced a total of 138,952 BBLs in that life span if I am reading this correctly. [I've posted the full production history for this well at this post: note the production after the original frack and the huge amount of production after the re-frack.]The reader asks:
The reader goes on:So how much potential is out there with old wells that can be re-fracked? [A rhetorical question.]
The Bakken has a lot of negatives based on the northern climate work environment and the distance to markets compared to southern US Basins. But on the other hand it looks like the updated frac jobs are using a lot of water. And the Bakken is sitting in the middle of a large lake on the Missouri River. It will take some effort to put in an underground distribution system with pumping plants on the lake to provide water for frac jobs and water flood secondary production but I bet in the coming years we will see that.
Original Post
This well came off the confidential list today:
- 31845, 879, CLR, Bridger 7-14H2,Three Forks 2nd bench, t8/17; cum 52K 10/17;
Many updates, including name changes (change in formation targets) with the Bridger/Bonneville wells. Regardless of whether wells were re-fracked or not, the important point to note is that many older Bridger wells have had a significant jump in production.
According to FracFocus this well was not re-fracked:
- 17088, 267, CLR, Bonneville 41-23H, Rattlesnake Point, t4/08; cum 160K 10/17;

Likewise, this well showed a jump in production, but no evidence that it was re-fracked:
- 19012, 365, CLR, Bonneville 2-23H, Three Forks, 24 stages, 2.5 million lbs; 4 sections, t12/10; cum 171K 10/17; huge bump in production 6/17; not re-fracked according to FracFocus;
