Abstract: A method of installing a mechanical barrier in a wellhead includes receiving a false bowl within a bowl of a casing head housing of the wellhead, generating a first sealed interface between the false bowl and the bowl with one or more first seals arranged about an exterior of the false bowl, receiving a plug within the false bowl, generating a second sealed interface between the plug and the false bowl with one or more second seals arranged about an exterior of the plug, and receiving a back-pressure valve within the plug.

Abstract: A contingency adaptor for a wellhead side-outlet with a damaged valve removal plug profile. The adaptor includes a neck on one end which may be extended into the wellhead side-outlet for creating a fluid seal between the neck and an inner surface of the wellhead side-outlet. A flange at the one end is configured to receive a gasket for creating a separate fluid seal between the adaptor and an outer surface of the wellhead side-outlet. The adaptor includes a valve removal plug profile at an opposite end to accommodate installation of a valve removal plug. The adaptor also includes a test port for pressure testing the connection between the adaptor and the wellhead side-outlet in order to confirm the integrity of the fluid seal(s) formed there between.

Abstract: A side-outlet adaptor assembly for repairing a side-outlet of a wellhead spool is disclosed. The side-outlet adaptor assembly includes an isolation sleeve having a first portion adapted to be received by the side-outlet and a second portion adapted to be received by an adaptor, the adaptor having a wellhead-side opening adapted to receive the isolation sleeve and a gate-valve-side (GV-side) opening adapted to receive a valve replacement (VR) plug, and a test port arranged on the adaptor for performing a pressure test of the side-outlet.
