Abstract
A technique facilitates actuation and use of a liner hanger in a wide variety of environments. Depending on the application, the liner hanger may be conveyed downhole within a casing located in a wellbore. The liner hanger comprises slips which may be set against the casing by applying a pressurized fluid through a liner hanger port to a liner hanger actuator. After the slips are set, the liner hanger may be actuated to form a metal-to-metal seal which blocks further fluid flow through the port, thus isolating the port during subsequent downhole operations.
