Abstract: An emergency casing slip hanger assembly that is adapted to be installed in a wellhead through a blowout preventer includes a slip bowl that is adapted to be releasably coupled to and supported by a slip bowl protector during installation of the slip hanger assembly in the wellhead through a blowout preventer, the slip bowl being further adapted to be positioned around a casing in the wellhead and landed on a support shoulder of the wellhead. A plurality of slips are adapted to engage with and support the casing, and a plurality of first shear pins releasably couple the plurality of slips to the slip bowl, wherein the plurality of first shear pins are adapted to be sheared by a pressure thrust load that is imposed on the slip bowl protector so as to drop the plurality of slips into contact with an outside surface of the casing.

Abstract: An emergency casing packoff assembly (170) that is adapted to be installed in a wellhead (100) through a blowout preventer includes an upper packoff body (171), a lower packoff body (174) releasably coupled to the upper packoff body (171), and a metal seal ring (175) that is adapted to create a metal to metal seal between the packoff assembly (170) and a casing (110) supported in a wellhead (100) when a pressure thrust load is imposed on the packoff assembly (170). The casing packoff assembly (170) further includes a lock ring energizing mandrel (173) threadably coupled to the upper packoff body (171), wherein at least a portion of the lock ring energizing mandrel (173) is adapted to be threadably rotated relative to the upper packoff body (171) so as to lock the packoff assembly (170) into the wellhead (100) while the imposed pressure thrust load is maintained on the packoff assembly (170).
