Shutting in a well increases the possibility of damaging the reservoir as well as the need for a workover. The change in pressure often damages the wall and casing, which increases costs. With a fracked well, all of this is multiplied. Shutting in a well is a case by case operation from a reservoir perspective. Based on the analysis [0] of the experts I talk with, much of the Permian Basin could be damaged not just at the well level, but the reservoir too. (Note that re-fracking is not the same as fracking a virgin field due to the new faults that were created. ) [0] - this is proprietary. Sorry for that, but this is analysis of particular plays, and that is guarded extremely tightly.
