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:
So how much potential is out there with old wells that can be re-fracked? [A rhetorical question.]
The reader goes on:
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
For newbies: this is an important post to help understand the the potential of the Bakken. I'm not going to go into it again but important concepts that are not being talked about by analysts with regard to the Bakken: total organic content (TOC); original oil in place (OOIP); multiple formations in the "Bakken": primary production; life history of Bakken wells that will produce for 30+ years (workovers; mini-re-fracks; neighboring fracks; re-fracks; microseismic arrays)
This well came off the confidential list today:
- 31845, 879, CLR, Bridger 7-14H2,Three Forks 2nd bench, t8/17; cum 52K 10/17;
Bridger/Bonneville wells have been updated.
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:
