I've quit posting parent-child uplift data for the most part; only when it interests me. It's so common in the Bakken, it's no longer news.
However, it should be noted, that for a number of reasons (which should be obvious) the parent-child uplift data generally involves parent wells and daughter/child wells targeting the same formation. In the Bakken, this is generally the middle Bakken.
Without comment or hypothesizing or explanation or anything else, there is another Bakken phenomenon: parent-child uplift involving different formations.
First example that I have specifically pointed out is at this post, a middle Bakken parent well and a Three Forks second bench well.
There have been numerous examples of similar results involving the middle Bakken and the Three Forks, first bench, and I guess I have pointed them out, but not as clearly as I'm pointing it out now. I need a new tag for this phenomenon, perhaps, "parent-child-inter-formation-uplift."
There's also another phenomenon for which I need a tag. Often, an older well is starting to show its age; the decline rate has leveled off and one gets the feeling that the well is beginning to "peter out." Then a neighboring well(s) is (are) completed, and the parent well gets an "extension." There is no significant jump in production (if there is a jump, it is subtle and folks would suggest something else is going on) but the decline rate is extended. The result: the EUR increases. Tag for now, "parent-well-new-lease-on-life" is way too long but I need a placeholder. Maybe "EUR_extended" or "EUR_EXT."
I suppose I could call all these Bakken phenomena, the Bakken gods smile on Harold Hamm. LOL. They may not be enough to move the needle for the operators, but mom-and-pop mineral owners love them and I'm sure the Slawson brothers get a chuckle out of them (or out of my naiveté ).
