Normal Resistivity Sonde
The Geovista digital Normal Resistivity Sonde can be used on its own or in combination with other Geovista sondes for efficient logging and correlation purposes. The SP can be recorded with the sonde either powered on or off, using the 16" electrode and a surface fish.

Dual Focused Resistivity Sonde
Provides a Medium and a Deep LL3 focussed resistivity log with finer
vertical resolution than the traditional Normal Resistivity sonde.
Performance is also better in higher conductivity mud and higher resistivity formations. This probe can be used on its own or in combination with other Geovista sondes
