PressureTracker™ Duo

At-Bit Annular Pressure While Drilling & Azimuthal Gamma Tools

Perform APWD measurement while responding to lithology changes to place your wellbore in the sweetest spots.



Key Features

  • Annular pressure right behind the bit

  • 16 sectors of gamma in memory

  • Up to 4 quads of gamma in real time

  • Total gamma measurements in real time

  • Fully self-contained sensor sub

More Features

  • Continuous inclination measurement

  • Downhole RPM measurement

  • 3-axis shock & vib monitoring in real time

  • Can be run either below or above motor (with proper connections)

Collar Size(s) Available

  • Available in 6-3/4 in. and 8 in. collar sizes

  • Modular packaging design permits battery, pressure/gamma sensor, or electronics replacement in shop or at rig site

  • Very short sub (2.92 ft or 0.89 m) optimizes bit steerability

  • Drop-in EM short-hop receiver retains MWD tool string retrievability

  • Powered by self-contained batteries with battery life up to 200 hours

Monitor dynamic pressure while performing geosteering with azimuthal gammas

Fully standalone module avoids any and all MWD-LWD integration hassles

Available in both standard version (150°C) and high-temperature version (175°C) 

  • Detect an over-pressured zone

  • Monitor downhole dynamic pressure to allow making timely adjustments to mud density to maintain optimum mud pressure



  • PressureTracker is a plug-'n-play module that can be dropped anywhere on a BHA (with proper connections).

  • PressureTracker uses our universal, field-proven EM short-hop communications system, eHop, for transmission of at-bit data across motor to the MWD system above the motor.

  • PressureTracker sensor module, electronics modules, and hatch covers fit all the different collar sizes.
