Casing Running Tools (CRTi 2-8.63)
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, ll/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 efcient.
Starting from the insertion diameter of the base tool, selectable sizes of integral jaws/dies are used to
congure the CRTi to support gripping casing of increasing internal diameter (decreasing weight). Through
the use of a patent pending extended reach die structure, the gripping diameter can be further increased
to include casing sizes much greater than the base tool.

1 Tool hoist rating is based on API Specication 8C; however, casing load limit is further constrained by local interaction of slip dies with casing, which must not exceed the
efciency indicated for individual slip die sizes to avoid excessive deformation. The slip to casing interaction hoist limit is calculated by multiplying the slip to pipe body load
efciency number by the casing hoist limit found in API Bulletin 5C2. From 5C2 the pipe body yield for 9.63” x 40.0 ppf L-80 Casing is 916,000 lbs. The slip efciency for die
81756 used to run this casing on the CRTi2-8.63 tool is 80%. Therefore, the casing hoist limit is 80% x 916,000 lbs = 732,800 lbs or 366.4 tons.
2 CRTi hoist capacity must be reduced by the pressure end load during circulation.
3 Torque capacity may be limited by slip die/casing interaction. Where torque factors are provided, multiply this factor by the desired casing weight in ppf then multiply the result by
the casing yield strength to determine the slip die/casing interaction torque limit. If no value is provided, tool rating will be limiting for all standard casing grades.
4 Maximum allowable compressive (push down) load applied to the tool. Some compressive load may be reacted through the coupling. This rating does not take into account
bearing load limitations of the coupling.
5 CRTi circulation pressure capacity is generally governed by packer cup pressure capacity. Pressure capacity may be less than indicated if alternative seal arrangements are used.
6 Overall tool length depends on seal arrangement.
7 Maximum ow rate is based on minimizing erosion rates when using typical uids. Erosion rates may vary based on uid contents. Please inspect tool bore regularly.
8 Common die sizes shown. Dies are available for all API casing sizes and weights with drift diameter above 7.38” are available.
9 Maximum pipe weight is dened by the API Specication 5CT drift diameter of the heaviest weight casing into which the CRTi assembled with the specied die set will t.
10 Indicated minimum pipe weight is based on the assumption that control of average pipe inside diameter over die grip interval does not allow pipe body area reduction
less than 3.5% from nominal and additionally takes into account tool wear allowances, die penetration, casing deformation and tool stroke.
