Patent abstract
A reamer shoe (1) for mounting on a tubing string has a reaming area (5) supporting a plurality of discrete reaming members (6) typically formed as simple geometrical shapes. The reaming members provide complete circumferential coverage of the shoe body (2) but the individual reaming members are non-continuous and do not fully extend either longitudinally along or circumferentially around the reaming area on the shoe body. The invention therefore provides a reamer shoe for reaming a bore in preparation for receiving casing, which is effective on rotation or reciprocation, regardless of direction or speed.
