• TrueDrill Real-time Downhole Autodriller System

    NOV’s TrueDrill™ real-time downhole autodriller system analyzes downhole drilling dynamic measurements and automatically adjusts the surface weight on bit (WOB) to maintain a desired downhole WOB (DWOB). The system uses high-speed, real-time downhole data to optimize your drilling parameters, achieve a higher ROP, and improve directional control while reducing downhole equipment and drill bit damage.

    The TrueDrill system is designed for use in conjunction with our downhole BlackStream™ EMS tool and the IntelliServ™ wired drillpipe system to provide closed-loop control of drill line payout using the measured DWOB measurement. The system uses advanced control algorithms to evaluate the system weight transfer characteristics and matches the drawworks payout response with the current drilling environment requirements. The TrueDrill system interfaces with the rig control system, providing set points for the rig autodriller that match the desired DWOB set point. The TrueDrill systems includes the control logic, safety case logic, operating platform, and user interface, which allows local or remote operation when interfaced using the WellData™ service. 

    This technology brings significant benefit to our industry, especially in the development of unconventional assets as drilling becomes slow and more challenging the longer the lateral. The TrueDrill system’s results have demonstrated that it significantly improves ROP and directional performance by delivering the required WOB.
