Abstract:
A wellbore system comprising a housing assembly and a hanger assembly. The hanger assembly comprises an actuation member that interacts with a portion of the housing assembly when the hanger assembly is positioned at a desired location in the housing assembly. The hanger assembly also comprises a load member that is adapted to extend between the hanger assembly and the housing assembly to enable the housing assembly to support the hanger assembly. The load member is carried into the wellbore in a retracted position. When the actuation member interacts with the housing assembly at the desired location, the actuation member actuates the load member to expand outward to extend between the hanger assembly and the housing assembly. The actuation member is adapted to transfer a lifting force from the surface to the load member to enable an over-pull test of the hanger assembly to be performed.
