ELG46: Electric Logging

This probe represents the latest generation of fully digital, high precision electric logging probes. As standard, the ELG46 probe provides long (64") and short (16") normal resistivity, single-point resistance (SPR) and self-potential (SP) data.

 

As an option, the probe can be supplied with a natural gamma detector to provide additional lithological information or for horizon correlation purposes. Widely employed in the domain of groundwater resources exploration and evaluation, the probe is suitable for use in formations having resistivities comprised between 10 and 25 000 Ω·m.
