Putting you in the zone
The SwivelMASTER® is a work string deployed tool that resolves potential sticking and loss of hook load 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.
With a reduction in sticking so crucial to operators in attaining TD, the SwivelMASTER reduces the hookload required to reach TD and pay zones and extends well construction boundaries, allowing application engineers to model the well and predict any issues before running in hole.
The significant increase in available force at the tool and reduction of drag also facilitates the deployment or retrieval of complex equipment in ERD wells – equipment that would previously have been lost in hole – providing significant savings in client time and cost.
Types:
SwivelMASTER Single Shot
The SwivelMASTER Single Shot configuration locks once with the ability to apply predetermined differential pressure at any time to allow full torque to be transmitted to the BHA below the tool.
SwivelMASTER Multi-function
The SwivelMASTER Multi-function configuration can be locked or unlocked multiple times as required with the application of predetermined differential pressure allowing full torque to be transmitted to the BHA below the tool.
SwivelMASTER Extreme
The SwivelMASTER Extreme configuration is a heavy duty version of the multi-function configuration and is suited for particularly long applications. It can be locked or unlocked multiple times as required with the application of predetermined differential pressure allowing full torque to be transmitted to the BHA below the tool.
SwivelMASTER CS
The SwivelMASTER CS is primarily used on horizontal or extended reach wells enabling the string above the tool to be rotated independently of the string below the tool and significantly reducing drag forces. This rotation allows more of the effective drill pipe and casing/tubing weight to be available to aid deployment of the liner or lower completion or other BHA to the final setting depth. The tool is designed for permanent installation in the casing/liner and drifts as per casing ID and provides pressure integrity. The SwivelMASTER CS is designed to rotate only in the right-hand direction. Rotation in the left-hand direction will lock the tool. Applying left-hand rotation and locking the tool will allow torque to be transmitted through the tool to the string below. This feature was designed primarily to facilitate an emergency release from a running tool or to back off from a casing connection.
SwivelMASTER ML
In comparison to the other SwivelMASTER designs, the SwivelMASTER ML has no hydraulic locking function and can freely be rotated to the right and locked to the left. The tool can also be supplied locked to the right and free to the left or with no lock – allowing it to swivel in either direction. The uni-directional function allows equipment to be deployed while rotating the upper string and enables left hand release functions on running tools to be used if required while still providing a dramatic reduction in work string friction above the tool.
