Halo Effect, Can The Halo Effect "Stretch" Across A Drilling Unit? Part II -- March 22, 2016

Before reading this post, read Part I regarding the Bridger wells. The same disclaimer applies as the one in Part I.

Now in Part II, we look at the production profile of another well. Note the huge jump in production between June, 2015, and August, 2015. It is startling. This well was drilled and fracked in 2010 and by 2015 it was an "old well" as far as Bakken wells go.

This is the production profile of this well:
  • 19013, 399, CLR, Bridger 2-14H, Rattlesnake Point, 4 sections, runs north, Three Forks, 21 stages, 2.3 million lbs, t12/10; cum 205K 1/16;
The graphic again of this area (and the description of this area at the linked post above):




#19013, I believe, is the horizontal labeled A-1 in the graphic above. Note that it is a Three Forks well. The horizontal tagged A-2 is a middle Bakken well and shows no increase in production over time; it shows the typical decline/plateau Bakken curve we have come to expect. 
 
Now look at this:
  • 29554, 1,018, Bridger 4-14H2, Three Forks, 30 stages, 6 million lbs, t1/16; cum 78K 1/16; fracked 7/11 - 7/20.
Yup. The horizontal tagged B-1 is #29554, a Three Forks well, and a Three Forks well that was fracked just prior to when A-1 had that surge in production.

I cannot explain why the A-2 (middle Bakken) well did not show a halo effect after two middle Bakken wells were fracked to the east. There may be other things going on with that well; it has a slightly strange production profile.
