Abstract
A wellhead is provided. The wellhead comprises a high pressure wellhead housing; a casing hanger assembly located within the high pressure wellhead housing; and a casing supported on the casing hanger assembly. The casing hanger assembly is arranged so that the casing is able to move relative to the high pressure wellhead housing. This may be to accommodate well growth experienced by the wellhead during use.
