| FEATURES |
| Formation conductivity measurement
in wet/dry boreholes or through plastic casing |
| Focussed measurements almost eliminates
borehole signal |
| PSD (phase-sensitive detector) discriminates
between magnetic susceptibility and conductivity signals |
| Highly stable measurement is almost
independent of temperature |
| Option of natural gamma for correlation |
| MEASUREMENTS |
| Formation conductivity |
| Natural gamma (optional) |
