Abstract: An embodiment of a tubing or casing hanger seal assembly includes a first carrier ring, a first energizing ring coupled to the first carrier ring and configured to set a first seal of the seal assembly in response to the application of a first load to the seal assembly, and a first lock ring configured to secure the first seal to the tubing or casing hanger in response to the application of the first load to the seal assembly, wherein the first carrier ring and the first lock ring include corresponding angled engagement profiles for providing a radial force against the first lock ring relative a central axis of the seal assembly in response to the application of the first load to the seal assembly.

Abstract: A packoff and a locking assembly installed in a bore of a wellhead component are provided. In one embodiment, a packoff includes inner and outer annular seals and an energizing ring shaped to be wedged between the inner and outer annular seals so as to apply a radially inward biasing force on the inner annular seal and a radially outward biasing force on the outer annular seal. In another embodiment, a locking assembly includes a lock ring that extends into a recess in a wall of the bore of the wellhead component and an actuator radially disposed between an inner component within the bore and the lock ring to retain the lock ring within the recess. The actuator can have an interference fit with the inner component to inhibit movement of the actuator between the lock ring and the inner component. Additional systems, devices, and methods are also disclosed.

Abstract: A locking assembly and a retaining ring for retaining the locking assembly within a bore of a wellhead component are provided. In one embodiment, a system includes an inner component disposed within a bore of a wellhead component and a locking assembly disposed within the bore to secure the inner component within the bore. The locking assembly includes a lock ring that extends into a recess in a wall of the bore of the wellhead component and an actuator radially disposed between the inner component and the lock ring. The system also includes a retaining ring that limits movement of the actuator along the inner component and maintains the actuator between the inner component and the lock ring to retain the lock ring within the recess. The actuator and the retaining ring have mating tapered surfaces that inhibit movement of the actuator out of engagement with the lock ring.
