A running tool assembly for installing a seal assembly in a wellhead housing includes a mandrel configured to couple with a conveyance string and including a central passage, a first piston slidably disposed about the mandrel and configured to releasably couple with the seal assembly, and a second piston slidably disposed in the central passage of the mandrel and including an annular seal that sealingly engages an inner surface of the central passage, wherein, when the running tool assembly is disposed in the wellhead housing, the second piston is configured to set an axially settable component in response to a pressurization of the central passage of the mandrel.

Seal assembly running tools and methods

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.

Running tool assemblies and methods

A system includes a running tool that has a tool body, a first piston configured to move a sealing member of a seal assembly between sealed and unsealed positions between the seal assembly and a first tubular, and a second piston configured to move a lock member between locked and unlocked positions between the seal assembly and a second tubular.

Hydraulic tool and seal assembly

A tubing or casing hanger assembly includes a tubing or casing hanger including a first key disposed on an outer surface of the hanger, and a locking member disposed about the hanger, the locking member including a first key disposed on an inner surface of the hanger, wherein the locking member includes a first position where the first key of the locking member is circumferentially spaced from the first key of the hanger, and a second position where the first key of the locking member circumferentially overlaps with the first key of the locking member to couple the locking member with the hanger.
