Swivelmaster

Resolve potential sticking and loss of hook load on drill strings by rotating the upper string without rotation or torque being applied to the string or BHA below.

Swivelmaster
Swivelmaster Overview
Practical Innovation

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.

Get in touch

Rubicon’s SwivelMASTERTM extends the current well construction boundaries on ERD and highly deviated wells.

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 multi-lateral 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.

Applications

SwivelMASTERTM can be repeatedly functioned from locked to swivel and locked again in various patterns and sequences depending on the tool set up.

Swivel Mode

After conversion to the swivel mode, this tool allows the string above the Swivel to be freely rotated in either direction in tension, neutral or compression.

Locked Mode

After conversion to the locked mode, all equipment below the tool can be rotated to the right or left.

Clutch mechanism allowing the string above the tool to be rotated independently from the string below

Heavy duty compression and tension bearing

High torque capacity clutch

Standard rotary connections

Available multi-function option

Long life rotary seals

Variations

Single Shot
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.

Multi-Function
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.

Mechanical
Mechanical

In comparison to the other SwivelMASTER® designs, the Mechanical SwivelMASTER has no hydraulic locking function and can freely be rotated to the right and locked to the left.
