| FEATURES |
| Stable, high-quality, semiconductor
temperature sensor |
| Graphite conductivity electrodes
resist corrosion and are easily cleaned |
| Optional natural-gamma detector |
| MEASUREMENTS |
| Fluid Temperature/ differential
temperature |
| Fluid conductivity/ differential
conductivity |
| Natural gamma (optional) |
| APPLICATIONS |
| Water |
Fluid salinity
Location of zones of different water quality
Water-well monitoring
Identification of zones of in-flow/out-flow
Temperature gradient
Water-level determination
Location of grout behind casing
Temperature compensation of other logs |
| OPERATING
CONDITIONS |
| Borehole type |
Open/cased hole, water-filled
In normal logging operations, the borehole should be allowed to stand for 24
hours to reach stable conditions and this probe should be run first. The log
is recorded downwards while running into the hole to minimise fluid disturbance. |
