Abstract
Techniques for an improved wellhead. The wellhead includes a casing hanger that suspends a casing string within a wellbore, a casing head, a retainer ring assembly, and a radial retainer fastener. The casing hanger includes external hanger threading that interlocks with internal tool threading in a casing running tool to facilitate manipulating the casing hanger via the casing running tool. The retainer ring assembly includes an external retainer groove and internal ring threading that interlocks with the external hanger threading on the casing hanger after the casing running tool is disconnected from the casing hanger to facilitate securing the retainer ring assembly to the casing hanger. The radial retainer fastener is secured through a radial fastener opening in the casing head into the external retainer groove on the retainer ring assembly to facilitate securing the casing head to the retainer ring assembly and, thus, the casing hanger.
