And GG showed few vids from the magic carpet ride over Brockham with few dosen of acid tanks around the well.

"Crucially, the Portland and Kimmeridge rocks also contain significant amounts of microscopic clay
particles bound within the rock. Consequently, as the lime dissolves, some of these clay particles are
released into flow paths within the rock. The “free” clay particles then migrate towards the well and
combine, forming a clay “sludge”, restricting or blocking some of the flow pathways, which can
significantly reduce the well’s performance.
Once blocked the flow pathways cannot be reopened."

Bet they are praying that fresh perforations are ok
But they will have to use acid "to clean the well" again won't they...
