In particular, the monitoring means monitors the space and volume within the lower annuluslocated between the inner surface of theintermediate casing stringand the outer surface of the inner casing string. Furthermore, the monitoring means provides the capability to retrieve and/or introduce fluid(s) into the annular space. The monitoring means provides a port, specifically a passageway, which extends upwardly from the annular spaceto an outlet located above the hangerfor the intermediate casing string. The passagewayis provided in a sleeve. The monitoring means includes a sensor located above the hangerwhich means that the fluid in the annular spacecan be monitored without the need for penetrating a casing in the wellhead.
