Casing Running Tool with Internal Grip (CRTi ™ )
Volant’s CRTi is designed for casing drilling or running with top drive equipped rigs to makeup, breakout,
reciprocate, rotate, fill/circulate, and cement casing and liner strings, reducing non productive time and
associated costs. This tool is mechanically activated in tension and both rotational directions solely by top
drive control using TAWG™ (Torque Activated Wedge Grip) technology.
This patented architecture puts control in the hands of the driller, reducing the need for third party support
to run casing. Simple intuitive operating steps for pipe engagement and release closely emulate the familiar
make and break steps used to run drill pipe – stab, rotate to the right to engage and reverse to disengage.
Similarly, rig-in and rig-out steps are simple, intuitive and efficient.
Starting from the insertion diameter of the base tool, selectable sizes of integral jaws/dies are used to
configure the CRTi to support gripping casing of increasing internal diameter (decreasing weight).
