ABSTRACT:
A method for cleaning well liners employing a jet carrier assembly having a plurality of jet nozzles spaced along its length each of said nozzles expelling a stream of fluid against the liner. The jet carrier is rotated at a specified rotational speed and moved at a maximum vertical speed which will produce streams of fluid having the energy needed to remove the foreign matter from any size liner with any sized slots or perforations and which will clean each point on the liner at least once.
