A technique facilitates utilization of a running tool system for use with a tubing hanger deployed at a wellhead. The running tool system may comprise a running tool which may be coupled to a hanger. The running tool may include a first sleeve which may be coupled to the hanger for moving the hanger in an axial direction. According to an embodiment, the running tool also may include a second sleeve which may be coupled to an adjustable landing ring disposed about the hanger. The second sleeve may be used to rotate the adjustable landing ring so as to lock the hanger in position.

Running tool system for a hanger

A system includes a housing of a wellhead, a hanger configured to be positioned within the housing of the wellhead, and a hanger retention system. The hanger retention system includes a key-slot interface having at least one retention segment configured to move between a collapsed position in which the at least one retention segment does not block movement of the hanger relative to the housing of the wellhead and an engaged position in which the at least one retention segment engages at least one corresponding slot to block movement of the hanger relative to the housing of the wellhead. The at least one retention segment includes a wavy cross-sectional shape at least while the at least one retention segment is in the engaged position that enables the at least one retention segment to move between the collapsed position and the engaged position.

Casing hanger retention system

A wellhead hanger assembly is provided. In one embodiment, a system includes a wellhead hanger, a running tool coupled to the wellhead hanger, and a torque sleeve positioned to transmit torque from the running tool to the wellhead hanger. The running tool can be in castellated engagement with the torque sleeve via a first set of castellations and mating slots, and the wellhead hanger can be in castellated engagement with the torque sleeve via a second set of castellations and mating slots. Additional systems, devices, and methods are also disclosed.
