TECH SPECS TUBULAR RUNNING SERVICES | TOTAL DEPTH® SERVICES


TorkDrive™ Electronic Modular Casing-Running and Drilling Tool Minimizes manual casing handling on offshore rigs by using mechanized equipment and wireless controls

Applications • Running and pulling casing, reaming with casing, and drilling with

casing in: – Operations with tapered casing strings – Deep wells – Deepwater wells – Extended-reach and deviated wells

• Operations with exceptional challenges and/or safety risks • Pushing down, reciprocating, circulating, and rotating casing during

casing-running, drilling-with-casing (DwC™), or reaming-with-casing (RwC™) operations

Features and Benefits • The TorkDrive electronic modular (EM) casing-running and drilling tool

mitigates differential sticking and other problems that can lead to nonproductive time.

• The tool enhances safety by removing conventional tongs, elevators, and associated personnel from the rig floor.

• Remotely operated bails eliminate the need for a stabber in the derrick. • The electronic control system directly integrates with existing rig control

systems to enable wireless operation from the driller’s cabin. • Exchangeable clamping modules accommodate a range of pipe sizes.

An external clamping module handles 4 1/2- to 10 3/4-in. tubulars; three internal clamping modules handle 9 5/8- to 22-in. casing.

• The modular design accelerates and simplifies rigging up and exchanging the clamping modules. The separate actuator and clamping modules reduce individual component size and weights on smaller rigs and increase efficiency when running tapered casing strings.

• The tool design enables switching between fill-up and circulation modes without repositioning the tool, which enhances operational efficiency.

• A sliding sleeve mechanism enables venting during casing-string fill-up to eliminate pressure buildup and prevent the sudden release of compressed air when the tool is removed from the casing.

• The flowback feature of the mud-saver valve enables automatic switching between fill-up and flowback modes, which eliminates the need to remove the mud-saver valve or reposition the tool.

• Wireless, remote control enables operations in any rig-floor environment.

• Multiple safety interlocks help to prevent dropped strings.

The TorkDrive EM tool directly integrates with existing rig control systems to enable operation from the driller's cabin, which reduces personnel on the rig floor.



TorkDrive™ Electronic Modular Casing-Running and Drilling Tool

Features and Benefits (continued) • The integral-compensator design helps to prevent thread damage by neutralizing tool and joint weight during makeup

or breakout. The integral compensator also enables the operator to quickly position the tool over successive joints for maximum efficiency. The long compensation stroke facilitates instant switching between makeup and breakout without repositioning the tool.

• The patented external clamping system evenly distributes and maintains gripping force during rotation, reciprocation, and push-down operations to enable running longer, heavier strings at high circulating pressures and to minimize the potential for pipe damage.

• The ability to hoist casing using a top-drive connection rather than elevator bails (links) enables rotational speeds up to 100 rpm for more efficient makeup cycles and DwC operations.

• A variety of torque-reaction-bracket designs adapt to any rig structure for faster operational response. • Integral torque/turn monitoring capabilities are completely independent of the top-drive control system and facilitate

safe, efficient troubleshooting. – The TorkSub™ electronic load cell provides accurate measurements of the applied torque and string weight to

indicate string sticking. – A high‑resolution turns sensor monitors turns/rpm during makeup, which enables operators to respond to

inadequate or excessive torque. – Both the TorkSub load cell and turns sensor are ATEX certified for use in hazardous environments, which

reduces the risk of gas ignition. • The tool is compatible with Weatherford TorkPro® software, which displays torque data and enables monitoring of

dynamic forces that could affect connection makeup.

Tool Description TorkDrive tools are the primary components of the Weatherford OverDrive™ system, which provides a safer, more efficient alternative to conventional casing installation. Each TorkDrive tool combines several conventional casing-running tools: a power tong, elevator, fill-up/circulation tool, and weight compensator. The TorkDrive EM tool is well suited for running and pulling casing, drilling with casing, and reaming with casing in offshore operations and other challenging well applications. It can be used to circulate, push down, reciprocate, and rotate the casing string while providing up to 80,000 ft-lb (108,465 N•m) of torque. Mounted on the top drive and operated remotely, the TorkDrive EM tool uses the rotational power of the top drive to make up casing. This configuration eliminates scaffolding, equipment, and personnel typically needed on the rig floor to run casing. The tool is capable of interfacing with any top-drive system and can be installed quickly, without modifications, to the top drive or rig structure. The Weatherford TorkDrive suite also includes the TorkDrive heavy-duty, compact, DT, and modular casing-running and drilling tools.
