摘要 A tubing shoe (30) comprising: a body (32) for mounting on the end of a tubing string; and reaming members (36) extending axially and circumferentially around the body, the reaming members providing substantially complete circumferential coverage of the body. When the tubing shoe is advanced axially into a bore, the reaming members (36) provide reaming around the shoe circumference, without necessarily requiring rotation of the shoe. A rotatable torque reducing sleeve or centraliser (38) may also be mounted on the body, typically rearwardly of the reaming members.
