CRTi® Internal Grip Casing Running Tool

Safe. Efficient. Effective.

Volant’s CRTi® casing running tools are fully mechanical and designed for casing running or drilling on top drive equipped rigs to makeup, breakout, reciprocate, rotate, fill, circulate and cement casing and liner string. From rig up to rig down and every step along the way, the CRTi reduces non-productive time and elevates your bottom line. Its patented architecture allows control to be in the hands of the driller for further improved safety and enhanced efficiency. As the most widely used top drive casing running tool in the world, our technology is proven where the figures add up—in the real world of field operations.

 

  • Compact, mechanical design removes multiple people and equipment from the rig floor.
  • Incorporates multiple functions into a single service and single piece of equipment, reducing non-productive time.
  • Mechanical activation by top drive control using TAWG™ torque activated wedge grip technology allows this tool to be operated by the driller.
  • Ability to rotate and reciprocate casing and liner strings reduces downhole friction.
  • Self-energized in torsion as well as hoisting to prevent slippage in either application.
  • Internal dies are designed to maximize the contact with the inside of the casing ensuring no slippage or distortion of the casing or liner.

*Speak to a Volant sales representative about increased hoist capacity options

Highflow CwD

  • Larger bore hole in mandrel for higher fluid flow for Casing while Drilling.

High Capacity Mandrel

  • Higher strength mandrel for higher rated hoist capacity.

ActiveSET™ Release

  • Mechanical release of latching mechanism through set-down load for faster connection makeup.

Inner-String Cement Tool

  • Designed to hoist the inner-string and provide a sealed flow path for cement to be delivered at the float shoe.

Mudsaver Valve

  • Installed between the casing running tool and casing seal, the Mudsaver Valve is designed to entirely stop fluid flow after fluid circulating or casing running operations.

Tether Swivel Accessory

  • A fall arrest device that tethers the casing running tool to the top drive in the event a connection backs off the casing running tool.
