The Staggering Bakken -- It Never Quits -- August 6, 2017

From a reader, another example of a jump in production after being shut-in for quite some time. I am too busy to complete this post so will come back to it later.

The well:
  • 21786, 1,494, XTO, Rink 12-4ESH, Garden, t4/12; cum 160K 6/17;
For now, the note from a reader (much, much appreciated for this example):
Another example: the Rink SE (#21786) was shut-in for about two years while other wells were drilled from this pad. The original frack zone had a chance to re-charge in addition to the recent fracking halo of nearby wells. In June, this well produced over 24,000 barrels of oil. It’s best month when completed in 2012 was less than half this volume. This is a Three-Forks 1st bench well in the Garden Field north of Watford City. 
The graphic:



There are a number of stories here; when I come back to this post, hopefully I will remember those thoughts.
  • This well was originally fracked in 2012; considered uneconomic in 2015 and shut in. All indications this well was not re-fracked: the reader suggests that it was not re-fracked;
  • the sundry forms suggest this well was not re-fracked; and,
  • no data at FracFocus to suggest any re-frac.
If this production holds (not a mistake, due to commingling reporting), this is quite remarkable.

For now, I only have time to post the production profile for the index well (#21786) since February, 2015 (production profile for other wells in the graphic at this post):
