SwivelMASTER®

The SwivelMASTER is a workstring deployed tool that resolves potential sticking and loss of hookload on drill strings by allowing the upper string to be rotated without rotation or torque being applied to the string or BHA below. A lockable mechanism also allows full torque to be transmitted to the BHA below. The result is a dramatic reduction in workstring friction above the SwivelMASTER. Increases length of open hole completion. Provides additional reservoir exposure and drainage. Enables wells from fixed locations to access by-passed oil. Reduces cost and risk. Removes the need for other friction reduction tools (like sub-based friction reduction tools). Eliminates stick slip when deploying critical components such as whipstocks and multilateral completions. Facilitates offshore well development from onshore or artificial island rig sites. Eliminates drag and provides force required for firing jars. Allows retrieval of equipment that would have been lost in hole by reducing drag in tension.
