Random Look At Interesting Way Of Drilling A 1280-Acre Unit -- The Bakken, October 18, 2015

Updates

February 11, 2017: graphic update of this area:



**************************

March 27, 2016: updating the graphic below. The index well for this discussion is #16510 -  this well is the >-shaped dual horizontal in the upper left hand side in the graphic below, and then again in the graphic farther down. It had a jump in production in June, 2015.  There were two sets of wells that ran north-to-south across the dual-lateral 16510. The horizontals coming from the 3-well pad to the west are DUCs (#30362, #30363, and #30364). However, two of the horizontals coming from the 3-well pad to the east (#23785, #23786) were fracked in June, 2015, according to Fracfocus.

Look at the production profile of #16510 around June, 2015:

Later, 7:14 p.m. Central Time: a reader writes regarding #16510:
It's been off the rod pump and flowing since the frac job on the CLR Ecopad to the north. 
Original Post
 
All four of these wells were originally COP/BR wells that are now operated by CLR, dual short laterals from same wellhead, different sections:


Here are some interesting data points:

16316, 280, CLR, Jensen 1-5H, Chimney Butte, t1/07; cum 199K 8/15;

Note the production profile of #16510, with nothing in the file report to explain the jump (see production in bold red). It is interesting that a CLR Ecopad to the north (#30362, #30363, and #30364, are on DRL status) has a rig on site (being fracked?), all of which run right under/over #16510 (halo effect).

In addition, interestingly enough, #29555 was fracked at exactly this same time. See data for #29555 farther down the post. This is production data for #16510:

I'm getting way beyond my comfort zone, but if this has to do with halo effect, fracturing, fracture lines, and porosity, we might be seeing something that the operators suspected some time ago. And, of course, with operators choking back and controlling monthly flow on producing wells, maybe nothing is going on, and this is all simply my imagination.

Here's the graphic:


(Note: in the graphic above, "#295" should be "#29555." Sorry.)
