Abstract
A running tool assembly for installing a hanger in a wellhead housing includes a first body configured to support the hanger, a second body coupled to the first body, a piston moveable relative to the second body, wherein the piston includes a first position and a second position spaced from the first position, and a piston chamber formed in the running tool assembly, wherein, when the assembly is coupled to the hanger and the hanger is positioned in the wellhead housing, the piston is configured to actuate from the first position to the second position in response to a pressurization of the piston chamber to engage a locking member disposed about the hanger and thereby lock the hanger to the wellhead housing, the assembly including a passage having a diameter that is equal to or larger in size than a diameter of a passage of the hanger.
