• FloDrift Real-Time Drift Tool 

    The FloDrift™ real-time drift tool is a simple and reliable instrument that provides real-time drift surveys during normal connection operations. The FloDrift tool delivers easy, cost-effective well inclination measurements in real time, and its survey-on-connection approach offers improvements in performance and safety when compared to traditional wireline inclination tools.

    The FloDrift tool allows you to take a real-time survey during each connection, reducing your overall well drilling costs. The tool’s survey- on-connection capability requires no additional rig time and eliminates extra rig- time expenditures.

    The FloDrift tool’s surface decoder uses a small footprint computer to automatically detect and decode survey inclination, and a user-friendly touchscreen monitor displays the information. All data is stored and viewable by rigsite personnel. Survey inclination logs are available to print anytime throughout the drilling process and at the end of the well.
