ABSTRACT:
The inside wall surface of a wall casing or tubing string is cleaned by providing an apparatus including a resilient flanged plug member and an elongated body having plural helical wraps of wire bristles disposed on the exterior surface thereof for engagement with the casing wall to provide a scraping and cleaning action. The apparatus is typically employed to clean the interior of the casing concurrent with displacing a column of cement composition through the casing for use in cementing the casing in place in the wellbore.
