<p>A liner hanger assembly seals with casing (22) and supports a liner (90) within a well. The tubular liner hanger body (50) and a tubular expander (40) may be positioned downhole at a desired depth on a running tool. An actuator assembly (12, 24) may forcibly move the tubular expander (40) into the liner hanger body (50), expanding the liner hanger body to seal and secure the hanger body to the casing string (22). The running tool may be released from the set liner hanger by an axially movable collet mechanism, such as ratchet ring (92) and a catch mechanism, such as threads (94). The running string thus need not be rotated to release from the set liner hanger.</p> |
