Can a Haynesville Shale well be damaged if it is shut-in while it still has a lot of pressure?

Ok, doc maybe one of the experts will see this and give us an answer.

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

Thanks Les,

  That is good to know.

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.

Suggest you Google: shut-in well damage problem

I have read so much lately (uugh AGAIN) that it makes my head spin........

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.

good blog on natgas!  thank for the link Bobi.

This area has suffered immense environmental degradation…
