Bobi, generally no damage should occur when a high pressure Haynesville Shale well is shut in.

Yes it can be. If something has happened to the casing in the horizontal (say that shale has blocked off the last 3 zones of the well) it will still show the pressure from the zones above.

here are other issues.  Different wells respond differently to shut-in.  In some cases, shut in actually can damage or choke back future flows from the well.  Other wells can see a surge of production when the well is restarted, recovering some of the lost production.  But in most cases, it is simply a deferral of cash flow.  That can impact the economics of the well investment.  A dollar received in 2021 is not worth the same as a dollar in 2012.  It’s that old present worth problem.
