Abstract
A system includes a hanger having a tapered radially-outer surface and a hanger sealing assembly configured to move between an unsealed position and a sealed position in which the hanger sealing assembly seals an annular space between the hanger and a housing of a wellhead. The hanger sealing assembly includes an annular sleeve, a first and second annular seal each comprising a respective tapered radially-inner surface configured to contact the tapered radially-outer surface of the hanger, and an annular seal-engaging sleeve. The annular seal-engaging sleeve is coupled to the first and second annular seals, and movement of the annular sleeve along an axial axis is configured to exert an axial force on the first annular seal, thereby causing the first and second annular seals to move axially and radially outward along the tapered radially-outer surface of the hanger to seal the annular space.
