It could quite possibly be that they stopped production so they could start drilling 3H

That would be a little unusual I think.  Horizontal wells in close proximity are shut in regularly before completion ops kick off.  The frac can communicate with adjacent or nearby wells.  I think that this is done to let those wells build up pressure but I'd like to hear Rock Man's take.

If wells are on the same drilling pad, they will definitely shut in the producing well.

But I have never heard of any operator in any play shutting in a producing well while drilling an offsetting horizonal location.

They may shut in producing wells during frac stimulation efforts on offsetting wells.

Thanks, Rock Man.  What is the reason for shut in of adjacent wells?  Does this lessen the chance of communication?

Shutting in offsetting wells during frac ops on new wells allows operator to "see" pressure increases tied to possible frac hits. Some operators may even put downhole sensors in producing wells to better see pressure hits.

In the Permian Basin, it was normal for operators to inform offsetting operators of upcoming frac jobs so that they would best prepare for possible frac hits.

How might a pressure hit impact an adjacent wells performance?

Frac hit could hurt offsetting well production due to major new influx of frac fluid and proppant.

This would cause more water production for "x" time plus possible proppant production (possible damage to surface equipment).

Over time after things stabilize, one may see an increase in gas production in the impacted well due to positive impact of the new offsetting frac.

Impossible to predict this in my mind.

Thanks.  I think the issue of "communication" between wells has been less of a factor in the Haynesville Play.  Much of what I have read deals with the Permian.  There have been a few instances of frac communication in the Haynesville that have resulted in emergency compliance orders from the Office of Conservation.

Distance between laterals playing a big part in non frac hit issues in Haynesville Shale.

Permian and Eagle Ford lateral offsets as short as 200-250' plays big part in frac hit issues in those oil prone areas.

It will be interesting in time if Haynesville Shale evolves into an infill drilling program to capture remaining unit reserves.

That is when frac hits will become big issue

I doubt that production was stopped due to drilling 3H. I haven't seen a drill permit on the RRC site for it yet. Believe me, I check regularly. I am going to our property on Tuesday and can do a well pad drive-by. I will report back if I see a rig or any activity of any sort.

Permian wells have been down spacing for some time while Haynesville operators have been up spacing with more intensive frac designs.  LA Haynesville spacing started at 8 laterals per mile (section) and is now 6.  This is the difference between ~660' separation between laterals in the beginning to ~880' as the standard currently.

The "Initial Potential" filing for the KEYDETS-A 47 4H well, which was submitted on 10/25/2022 with Tracking No. 279526, was approved on 1/6/2023.

The "Approved" Form G-1 has more information about the initial test measurements than the "Submitted" G-1. I also noted that the Form P-16 (Acerage Designation) had changed from an earlier version.  There may be other documents with changes I didn't notice.
