A system for performing subterranean operations comprising:
- a liner hanger positioned within a casing,
- wherein the liner hanger comprises a spiked portion having one or more metallic spikes,
- wherein the one or more metallic spikes comprise a flat portion,
- wherein at least one of the one or more metallic spikes is expandable, and
- wherein the flat portion of each of the one or more metallic spikes interfaces with the casing when the spike is in the expanded position;
- and
- a liner coupled to the liner hanger.
A method for coupling a liner to a casing of a cased wellbore in a subterranean formation comprising:
- coupling a liner hanger to the liner,
- wherein the liner hanger comprises a spiked portion having a first metal spike;
- lowering the liner and the liner hanger downhole through the casing;
- and
- expanding the first metal spike,
- wherein expanding the first metal spike couples the liner hanger to the casing.
