CRTe® External Grip Casing Running Tool

Volant’s CRTe® 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. Ideal for applications that require large hoisting loads and torsional capacity, the CRTe dies compress radially and engage the outside surface of the casing below the coupling, allowing it to then be hoisted, rotated and circulated using the top drive. From rig up to rig down and every step along the way, the CRTe 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, fill and circulate casing and liner strings reduces downhole friction.
  • Self-energized in torsion as well as hoisting to prevent slippage in either application.
  • External dies are designed to maximize the contact with the outside of the casing ensuring no slippage or distortion of the casing or liner.
