This three-coil slim hole induction tool was designed to provide conductivity and converted resistivity logs in open boreholes or PVC/plastic cased holes with casing sizes 5.08 cm (2 in.) or greater. The probe measures the rock conductivity in borings and wells within a zone of 25.4 to 127 cm (10 to 50 in.) from the well, but is not sensitive to the borehole fluid, casing, or grouting materials. The tool can also be used in air filled holes to measure the conductivity response. In addition, the tool also simultaneously records natural gamma ray in API units or CPS for determination of clay content and radioactivity measurements.
