Sondes / Probes




Dual Focused Resistivity Sonde

Product Information

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.
