Linear hanger assembly
This patent describes a hanger assembly securable to a workstring for carrying a liner conduit in a subterranean well and settable within a casing string. It comprises: an elongated tubular housing; a series of circumferentially extending slip elements carried exteriorly around and by the housing and axially movable relative to a slip seat from a radially retracted position to a radially spaded position for gripping engagement with the casing string; and each of the slip elements having circumferentially subscribed exteriorly protruding non-buttress teeth defined thereon, the teeth being symmetrical to both pus and pull forces applied through the assembly by either the work-string or the liner conduit subsequent to setting within the casing string; wherein the assembly is moved to a set position relative to the casing string by application of hydraulic pressure in a first predeterminable amount to transmit and apply a setting load to the slip elements; and further comprising compressive biasing means movable to a compressed biasing means movable to a compressed condition by mechanical manipulation of the workstring subsequent to movement of the assembly to the set position to transmit a second load to the slip elements in excess of the setting load; and locking means for locking the setting and second loads into the slip assembly.
