May 10, 2017: still no FracFocus report or anything in the file report to suggest this well was re-fracked.

Later, 9:12 p.m. Central Time: this one reminds me of #17356. I don't think it's a coincidence that this "case" and the #17356 case are both BR wells. To the best of my knowledge, #17356 was not re-fracked (I could be wrong, but I don't see the data) and yet it also has some huge monthly production data after neighboring wells were fracked.

Original Post

 

An old, old well. No re-frack data over at FracFocus yet. This one had to have been re-fracked (no data yet to confirm that) or neighboring wells on conf status were recently fracked; if so, this is quite a story. We might not know for several months.

The four neighboring wells to the west were recently fracked; there are two questions:

• were the three wells to the east (still confidential) also fracked; and,
• was 19548 re-fracked? 

If #19548 was not re-fracked this will be quite a story:

• 19548, 508, CLR, Gudmunson 1-26H, Elidah, 24 stages, 2.4 million lbs, t10/11; cum 175K 10/16 -- taken off-line early 12/16; API 33-053-03264;

This well is five or six years old; surrounded by other wells that have been fracked and will be fracked. See graphic at this post. Were #30991 - #30993 (inclusive) recently fracked? The production in 12/16 - 1/17 greatly exceeds production when initially fracked. 

With a production jump like this, this well had to have been re-fracked, but as of 3/17, there is no data at FracFocus reporting a re-frack nor is there any evidence of a re-frack in the file report.
