Abstract

Various wellhead assemblies are provided. In one embodiment, the wellhead assemble includes a seal assembly (42) that seals against an inner surface (46) of a wellhead hanger and against an inner surface (34) of a wellhead body. The wellhead hanger can be sized such that the upper portion of the hanger has an outer surface that abuts an inner surface of the wellhead.
