Rotating wellhead hanger assemblies are provided. In one embodiment, a wellhead hanger assembly includes a casing hanger and a casing hanger running tool coupled to the casing hanger. An exterior surface of the casing hanger includes a recess and the casing hanger running tool includes a dog that extends inward from the casing hanger running tool into the recess of the exterior surface of the casing hanger. Engagement of the dog with the recess of the casing hanger facilitates synchronous rotation of the casing hanger and its running tool. Additional systems, devices, and methods are also disclosed.

A running tool with an overshot sleeve is provided. In one embodiment, a system includes a running tool and an overshot sleeve including a first portion threaded onto the running tool and a second portion. The first portion and the second portion are connected together in a manner that allows the first portion and the second portion to rotate with respect to one another. The second portion of the sleeve can engage an additional component, such as a casing hanger, and the running tool and the overshot sleeve can be configured to selectively convert rotation of the running tool into axial motion of the overshot sleeve with respect to the running tool. Additional systems, devices, and methods are also disclosed.

Running tool with overshot sleeve

Present embodiments include a sealing system configured to be disposed about a first wellhead component, wherein the sealing system includes a first seal and a pre-charging system configured to exert a first initial lateral loading force on the first seal to increase a first initial seal contact pressure of the first seal.

Energized seal system and method

Rotating mandrel casing hangers are provided. In one embodiment, a system includes a casing hanger having a lower end configured to engage a casing string and a running tool configured to engage the casing hanger. The system is configured to facilitate rotation of the casing hanger within a casing head to rotate the casing string while cementing the casing string within a well. Additional systems, devices, and methods are also disclosed.
