• e-Wildcat Electronic Autodrilling System

    NOV’s e-Wildcat™ electronic autodrilling system delivers superior performance, including reduced bit wear, improved safety, enhanced rig efficiency, and a higher quality wellbore.

    The e-Wildcat system with RigSense™ information capabilities provides constant force and payout to generate a higher quality wellbore and optimize drilling parameters. The system smoothly controls payout via brake handle, using precise stepper motor control technology and multiple-parameter drilling in “auto drill” mode. In addition to the Delta-P technology and proven reliability, our e-Wildcat system expands control parameters to include ROP, weight on bit (WOB), and torque. The “time drill” feature allows drilling at a specific rate, addressing specialized requirements of casing sidewall milling and sidetrack operations within multilateral openhole wellbores.

    The robust design of our e-Wildcat system provides the precise control and performance needed in your conventional and unconventional drilling operations—the high count stepper motor and improved control algorithms improve your drilling control and results.

    Features/Benefits

    Driller can have a set point that will limit torque and reduce stalling

    • Saves time by no longer having to come off bottom to release stored torque

    Control mode identification can display active control loop and allow parameters to be selected

    • Increases accuracy to maximize performance gains

    Digital control can increase the accuracy to a set point

    • Provides more precise slow drilling

    The mud-pump hydraulics safety cutout will stop the line payoff if there is an insufficient mud-pump rate

    • Prevents dry drilling from burning up drill bits

    Drum movement protection electronically senses the driller starting to hoist and will disconnect if left engaged

    • Secures the equipment and keeps the driller safe

    Drill stop point makes the system drill to a depth entered by the driller and no farther

    • Helps prevent rig floor collisions to keep the equipment intact

    The patented bit protect feature automatically controls bit placement and reaming speed

    • Saves time and money with longer bit life

    Time drill feature allows control of drilling amounts and time taken to reach stop points

    • Assists the driller with tasks such as kickoff, sidetracking, and milling
