Resistivity

AWR (Array Wave Resistivity)

The AWR tool is a fully compensated dual frequency (2 MHz and 500 KHz) resistivity tool with 12 diameters of investigation from 3 sensors at spacings of 15”, 25” and 45”. Three spacings provide robust quantitative data for invasion corrections and processing without dielectric assumptions, or single frequency results.

Survivor AWR

The AWRTM tool is a dual frequency (2 MHz and 500 KHz) resistivity tool that provides 12 diameters of investigation from 3 compensated transmitter/receiver spacings at 15” 25” and 45”.

CWR (Compensated Wave Resistivity)

PathFinder’s CWR tools offer the greatest diameter of investigation of any 2 MHz resistivity tool in the industry! It provides 4 resistivity curves (2 phase and 2 attenuation) with symmetrical receiver spacing at 25” and 55” for maximum depth of investigation.
