Temperature and conductivity anomalies within a borehole b307137990provide useful indications on the fluid circulation of aquifers.

Other parameters such as salinity, redox, dissolved oxygen are indicative of the fluid quality .

The log of temperature and conductivity can be performed up to a pressure of 200 bar, the remaining parameters up to 20 bar.

APPLICATIONS:

♦ Hydrogeology studies and geothermal resources;

♦ Planning slotting sections of wells and piezometric pipes;

♦ Anomalies gradients measurements, localization of fluid interfaces and depth of sampling;

♦ Measure temperature evolution during the grouting process of casing (24-36 h).
