Key Features

  • Up to 12 fully compensated propagation resistivity measurements at 400 kHz, 2 MHz, and 4 MHz

  • All measurements are fully compensated for borehole or temperature effects
  • Resistivity range up to 4,000 ohmm

More Features

  • 3-axis shock & vib monitoring in real time

  • Gamma measurement (optional)

  • H2S-resistance upgrade available

Collar Size(s) Available

  • Available in 2-3/8 in. and 3-1/8 in. collar sizes

  • Ruggedized design improves tool survivability in excessive shock and vib environments

  • Modular packaging design permits electronics replacement in shop or even at rig site

Bring high-accuracy propagation resistivity to coiled-tubing drilling ops

Can work with top-mounted pulser or bottom-mounted pulser

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



  • Monitor bed boundary crossing while side tracking

  • Detect approaching reservoir boundaries

  • Monitor water zones and avoid contact

  • Refine the earth model with the high-definition resistivity measurements
