Abstract

A casing hanger apparatus includes an upper ring, a lower ring, and a packing element positioned between the upper ring and the lower ring. The packing element has an annular body with a wedge-shaped cross-sectional geometry. Bi-directional pressure intensification (BPI) pins are arranged around the casing hanger in an angularly spaced apart configuration, where the BPI pins extend axially from the upper ring through holes in the packing element to the lower ring. In some casing hanger apparatuses, a bushing member is positioned axially between the upper ring and the lower ring, where the BPI pins also extend axially through the bushing member.
