Hole Opening

SwivelMASTER

 

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.

Variants:

SingleShot

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.

Multifunction

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.

Extreme

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.

Non Hydraulic SwivelMASTER

In comparison to the other SwivelMASTER designs, the Non Hydraulic SwivelMASTER 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.
