• TDS-10SH Top Drive

    The TDS-10SH Top Drive is a portable top drive designed for land-based drilling operations.

    Description

    The TDS-10SH Top Drive is a portable top drive designed for land-based drilling operations. This NOV top drive combines the increased performance of AC drilling motor technology with a compact drilling system. These features allow the TDS-10SH to support increased drilling productivity for smaller land-based drilling operations.

    • Portability: The AC motor, combined with the S-type integral swivel and unique guide beam arrangement, form one of the most compact drilling packages available.
    • Power: The TDS-10SH is designed around a 400-HP AC drilling motor that can produce 22,388 ft-lbs (30,218 Nm) of continuous drilling torque. The top drive also supports 42,680 ft-lbs (57,866 Nm) of make-up and breakout torque using the PH-55 Pipe Handler.
    • Compact Design: The TDS-10SH is compact enough to operate safely in a standard 136-ft mast while also providing 250 tons of hoisting capacity. The portable design means that rig-up and rig-down operations take only a few hours. The top drive can easily integrate into existing rigs with minimal cost and rig modifications.

    Features/Benefits

    • High Performance: The AC motor and Variable Frequency Drive of the TDS-10SH provide precise speed and torque control for low speed drilling. The extended range of usable horsepower characteristics of AC motors is perfect for taking advantage of modern PDC bits. The higher intermittent torque levels of the AC motor also supply greater breakout and make-up torque than comparable DC and hydraulic powered top drives.
    • Portability: The AC motor, combined with the "S"-type integral swivel and unique guide beam arrangement, form one of the most compact drilling packages available. This compact design is highly mobile and fully transportable between rigs. Once installed, rig-up or rig-down can be performed in a matter of hours.
    • Low Maintenance: Since AC motors have no brushes, brush gear, or commutator, drilling motor maintenance is greatly reduced. And no stand-alone hydraulic supply, fluids service loop or additional standpipe are required, thus reducing accessory costs and improving reliability.
    • Improved Economy: The increased efficiency of the NOV AC motor and drive system reduces rig fuel consumption, improving overall rig economy. An on-board hydraulic power supply eliminates the need for costly remote auxiliary hydraulic power, derrick piping, and fluids service loop.
    • Increased Safety: The Advanced NOV system for making/breaking connections with the drill motor and pipe handler greatly increases crew safety.
    • Faster Directional Drilling: The improved drill bit control possible with the full rotational capability of NOV Top Drive systems increases the speed of building hole angles in directional and horizontal wells.
    • Increased Environmental Safety: A closed loop fluid system reduces the risk of contamination and fluid spill into environmentally sensitive areas by eliminating the need for draining and refilling during rig moves.
