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.

Abstract: The present invention is directed to a split locking ring for wellhead components. In one illustrative embodiment, the device comprises a first internally threaded wellhead component, a second wellhead component, at least a portion of which is positioned within an opening in the first wellhead component, and a rotatable split lock ring comprised of at least two externally threaded sections, wherein at least a portion of the sections of the split lock ring are positioned between the first and second wellhead components and rotated to threadingly couple the sections of the split lock ring to the first wellhead component and thereby secure the second wellhead component to the first wellhead component.
