Dual Induction Logging Tool (DILT)

The Dual Induction instrument is used to obtain formation conductivity measurements in low salini­ty or oil-based drilling fluid environments. Using transmitter-receiver coil pairs, it provides Deep and Medium resistivity measurements used for fluid saturation calculations.

The DILT provides conductivity measurements at 2 different levels of investigation and resistivity values. This tool is designed to provide resistivity measurements necessary to estimate the effect of invasion, to obtain the true formation resistivity.




  • Invasion Profile determination
  • Water Saturation measurement
  • Identification of fluid contacts
  • Combinable with other Gallop tools
  • Performs well in low salinity muds
