General
I have a fairly bad manganese problem in a couple spots and have well casing perforations get stopped up from it. What methods has anyone hired or used for cleaning casings and/or perforations that have worked well?

I have used WellJet (Welljetbyhpc.com they will travel) to clean numerous wells for me. They use super high pressure water (16,000-20,000 psi) to loosen up the fouling that you see on the casing as well as getting energy out into the gravel pack.
Once they are done, you will need a good drilling contractor to come in and dual swab/ airlift all the loosened material out of the well.
