Our FloSurvey™ real-time survey tool capitalizes on the success of our proven FloDrift™ product, which features our patented Pressure Release Encoding System (PRES™) technology for easy, cost-effective transmission of downhole information.

The FloSurvey tool provides real-time surveys during the normal operation of making a connection, saving you both rig time and money. The FloSurvey tool is less expensive than a full measurement while drilling (MWD) system, and our approach offers improvements in performance and safety compared to traditional wireline surveys.

Our FloSurvey tool further extends the PRES and FloDrift technologies, displaying inclination and azimuth in less than 90 seconds from pumps on—the fastest real-time azimuth decoding in the industry. Additionally, PRES technology works well in noisy surface-hole sections, unlike most MWD decoders that struggle to provide accurate measurements in noisy environments.

The FloSurvey tool automatically compensates for most flow-rate and mud-density changes, allowing operators to change mud flow and weights without affecting decoding performance. Memory-logged survey data can be processed after the tool is back on the surface if additional quality assurance or enhanced survey accuracy is required. The FloSurvey surface decoder uses a small footprint computer and a user-friendly touchscreen display that automatically detect, decode, and display survey inclination and azimuth. All real-time transmitted surveys and well survey logs are viewable on the drill floor, and the data are obtainable for printing anytime.


  • Real-time surveys on connection
    • Provides real-time surveys during the normal operation of making a connection
  • Inclination and azimuth displayed in less than 90 seconds from the time the pumps are turned on
    • Provides the fastest decoded survey in the industry—accurate inclinations with a resolution of 0.1° and range up to 20° (0 to 180° memory)
      • Azimuth resolution of 1° and range of 0 to 360°
      • Azimuth accuracy of >5° ±2° (memory), ±3° (real time)
  • Optimal magnetic spacing of sensors
    • Runs in nonmagnetic drill collars with PRES telemetry FloValve housed within the standard API borebacks
    • Shorter 15-ft collar allows adequate magnetic spacing for most vertical wells
  • Automatic and accurate decoding of surveys
    • User-friendly operation—no additional driller involvement needed to obtain survey during the connection process
    • PRES telemetry eliminates the need to decode multiple pulses to obtain inclination and azimuth measurements
