Abstract
A setting tool and a liner hanger for setting a liner hanger in well bores traversing earth formations where the setting tool can be hydraulically operated and released from the liner hanger or alternatively, can be mechanically operated and released from a liner hanger. The tool is provided with bypass areas in the liner hanger and locates the tieback sleeve below the liner hanger. The setting tool incorporates most of the expensive setting mechanism in the setting tool and is not a part of the liner hanger. Thus, the setting mechanism is therefore removable from the wellbore and can be reused on other liner hangers.
