A684 Temperature / Fluid Resistivity

TEMPERATURE
Temperature is sensed by a fully encapsulated AD590 temperature sensor
Located in the stainless steel probe at the bottom of the tool. The sensor produces a current directly related to the temperature.
All temperature logs should be recorded on the down run of the borehole to avoid disturbing the temperature equilibrium between hole fluids and the formation. Temperature logs are used in the determination of water level, detection of casing leaks, fluid entry or exit detection. Heat flow anomalies and minute fluid or gas leaks will also be readily detected.

FLUID RESISTIVITY
Measurement of fluid resistivity within cased or uncased boreholes can not only identify changes in the resistivty gradient but also measure minute changes in water resistivity/quality through a differential fluid resistivity log. The sensitivity of this tool can detect large or small resistivity anomalies.

As with all logs it is important to maintain a consistent logging speed to ensure excellent quality results.
