A technique facilitates deployment and operation of a casing hanger. A ratchet mechanism may be positioned between the casing hanger and a running tool. The ratchet mechanism may comprise a center body section located between a first cam, e.g. a lower cam, and a second cam, e.g. an upper cam. The first cam is constructed for releasable engagement with the casing hanger and the second cam is constructed for engagement with the running tool. The first cam has a cam profile which causes rotation of the casing hanger when the running tool is rotated in a first direction and which causes the ratchet mechanism to release from the casing hanger when the running tool is rotated in a second direction. Additionally, the second cam also may have a cam profile configured to force the ratchet mechanism toward the casing hanger when the running tool is rotated in the first direction.

Rotating hanger system with ratchet mechanism

An adjustable fracturing system is provided. The system includes an adjustment joint configured to be varied in length to facilitate coupling of a fracturing manifold to a fracturing tree. In one embodiment, the system may also include the fracturing manifold and the fracturing tree. Additional systems, devices, and methods are also disclosed.

Adjustable fracturing system

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.

Rotating wellhead hanger assemblies

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

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.
