Abstract

A method of cleaning a liner top 72, the method comprising the steps; inserting a cleaning tool 10 into a liner; running the tool and liner 66 together into a well bore; setting the liner at a casing in the well bore; rotating and/or reciprocating the tool to clean an inner surface of a PBR on the liner with cleaning elements 24a thereon; pulling the tool from the PBR, so that cleaning elements 24a move outwardly by means such as leaf spring 40 to contact neighbouring casing 68 and the liner top 72; and rotating and/or reciprocating the tool to clean an inner surface of the neighbouring casing 68 with the cleaning elements 24. A surface 54 on the cleaning element 24 includes a mill 80 which, when it contacts the top 72 of the PBR 66, can dress the top, acting as a top dress mill when the string is rotated.
