Borehole Cleaning

What is it?

Also known as flushing, swabbing, surging or jetting all are aimed at removing drilling fluid that has covered (or painted) the borehole walls and gravel pack. It is important to remove this drilling fluid as it stops water entering the borehole. The same methods are also used after a few years when the amount of water from the borehole drops due to a build up of silt at the screen and gravel pack.
