Dual Lateral Logging Tool (DLLT)

Using an array of electrodes to focus the measuring current into the formation, the Dual Laterolog provides both Deep and Shallow formation resistivity measurements in conductive borehole envi­ronments. An SP reading is also recorded by the instrument.

The measurement is particularly suitable for high resistivity forma­tions. Both deep and shallow readings allow for visual identification of permeable formations. 





  • Obtains invasion profile
  • Estimates water saturation
  • Combinable with other Gallop tools
  • Can distinguish formations bearing conductive fluids (including salt water and mud filtrate) from formations with non-conductive fluids (oil and gas). 
  • Spontaneous Potential (SP) reading included
