Abstract


Reference is made to tests on models carried out with the use of a
focused current electrode arrangement.
The tests were realized for an anomalous resistive parallelepiped
shaped body immersed in a homogeneous isotrope conductive medium.
Depth, thickness, height, and width of the parallelepiped were allowed
to vary. Thus it was possible to individualize the influence the parameters
had on the anomalous body.
Utilizing analogous laboratory experiments which were carried out
with the use of the Schlumberger arrangement it was possible to compare
the two results obtained. To this end, the maximum values of the
anomalous curves and the resolution index W/L were utilized. The comparison
showed the advantages that can be obtained with a focused
current arrangement especially with regard to the depth of the investigation.
Even the variations on the thickness were more evident with the
focused arrangement.
