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.

Abstract: A well completion system comprises a tubing head which includes a central bore that extends axially therethrough and at least one fluid port that extends through the tubing head to the central bore, a tubing hanger which is supported in the central bore, an alignment pin which is mounted in the fluid port and which comprises a key portion that protrudes into the central bore, and structure for engaging the key portion to orient the tubing hanger relative to the tubing head. In this arrangement a blind flange may be secured to the tubing head over the fluid port to effectively seal the fluid port from the environment.

Abstract: A casing hanger assembly is disclosed which includes a bottom member which centralizes a casing string within a casing head and a top member of a conventional slip-type casing hanger design. The bottom member functions to rigidly centralize the casing string inside the casing head while absorbing any side bending load induced by movements of the casing string. The top member, set on top of the bottom centralizer member, supports and transfers the weight of the casing string to the casing head.
