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.
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.
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.
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.
