  • Resources Resources

The 8.25-in. BlackBox™ and BlackStream™ EMS tools, available in either memory-recording or IntelliServ data-streaming configurations, are capable of an array of measurements, including multi-axis vibration, load, pressure, bending, and rotation. Our collar-based EMS tool can help deliver custom solutions for drilling challenges such as stick-slip, whirl, and borehole quality to optimize drilling performance and reduce well delivery costs.


  • Proprietary and patented depth/pressure compensation
    • Ensures the highest accuracy of weight and torque measurements
  • Maximum, minimum, and mean values for load measurements statistically recorded up to 800 Hz
    • Delivers accurate data resolution—visualize trends in downhole behavior and identify key optimization methods
  • Short, versatile 15-ft sub length
    • Allows for versatile placement in the BHA or drill string—flexibility to collect data from various locations
  • Nonmagnetic tool
    • Reduces interference with directional equipment and increases tool placement options for data capture
  • Self-contained power supply
    • Allows tool to be run independent of other downhole equipment
