May 18, 2019: #26419 and #17356 are about 100 feet to the west of #26007 and #26006.
November 28, 2017: regardless of what's going on, this is an incredible well:

Look at this post. I am still unable to explain the jump in production in 9/16 of #25961. [Update, January, 2018: just prior to the jump in production: a work-over rig on site, and a new pump put in; no evidence that is was re-fracked; no sundry form to suggest a re-frack and FracFocus does not show a re-frack.]
Note that all three wells on this 3-well pad were taken off-line 8/16, and then brought back on line in the next month or so. Generally, when one sees that, it means that a neighboring well was fracked.
In this case, when I originally looked at these three wells, I could find no evidence of a neighboring well being fracked.
Today, I took another look.
It turns out a neighboring well was fracked 8/16, the very month that these three wells were taken off-line.
But it still doesn't make sense.
All three wells showed a bump in production, though the Three Forks wells showed a minimum jump in production whereas the middle Bakken well showed a hug jump in production (from 5,000 bbls/month to 14,000 bbls / month). The jump in production did not last particularly long, but it's hard to believe the jump in production from 6,000 bbl/s month to 14,000 bbls/month was due to "recharging" when the well was off-line for less than a month.
I found the well that was fracked in 8/16 that was probably the reason for BR taking these wells off-line:
- 31310, 1,179, Hess, AN-Brenna-LW-153-94-3130H-1, Antelope, Sanish pool (Three Forks), t9/16; cum 176K 6/17; a "small" frack, only 3.1 million gallons of water; 13% sand by weight;
Again, there are many, many problems with this:
- distance between horizontals;
- different formations;
- closer horizontals, targeting same formations, jump in production much less than #25961
