For newbies: wells in the Bakken will be producing for 35 years. During that period of time, individual wells will undergo workovers, small re-fracks, major re-fracks, and will be impacted by neighboring fracks.
This is a great example of such a well. This well was drilled back in 2011. It has never been re-fracked. On two subsequent occasions, this well has shown a significant jump in production. The jump in production may not have lasted long (that's in the eye of the beholder) but each jump in production changes the slope of the decline curve; and, increases the EUR. In addition, mineral owners/stakeholders see a nice jump in their monthly royalties.
