COMPARISON BETWEEN SCHLUMBERGER ELECTRODE ARRANGEMENT AND SOME FOCUSED ELECTRODE ARRANGEMENTS IN RESISTIVITY PROFILES

The "Istituto di Geofisica Mineraria" has carried out experiments on focused electrode arrangements in situ in resistivity profiles during the investigations of underground cavities and in laboratory tests on models placed in electrolytic tanks containing cylindrical or parallelepiped bodies. Abnormal potentials due to surface noise, assuming the surface to be a hemisphere with an equational plane coinciding with the surface of the earth, were calculated for focused arrangements. Similar anomalies were calculated for Schlumberger arrangements. Model tests were also used for studying focused and Schlumberger arrangements. The results of the comparison between the two arrangements (relation between anomalies and surface noise) have shown that, generally, focused arrangements give better results even in the presence of surface noise.
