Resistivity Measurements

Electrical measurement is one of the most used geophysical methods, for determining the hydrogeologic investigations, and also determining the depth of rock and identifying the lithology of the subsoil. The usual practice in the field is, to apply an electrical direct current (DC) between two electrodes A and B implanted in the ground and to measure the difference of potential between two additional electrodes M and N that do not carry current. Different measurement technique is developed to amount of electrod and the geometry of array, these are; Shlumberger, Wenner, Dipol dipol, Pol dipol techniques.

Resistivity measurement studies are executed with AGI R8. System has 8 channels, 56 electrodes.
