MS-ICDP (Logging tool)

Model id: Magnetic Susceptibility, Antares, SN: 1118001


  • magnetic susceptibility
  • temperature
  • total natural gamma

Purpose: magnetic susceptibility of the rock

Characteristics: a coil generates a magnetic field that magnetizes the rock, which in return induces a current in a receiver coil; MSUS [10-4 SI], TEMP [°C], GR [gAPI]
