Abstract

The paper considers the manifestation of electromagnetic (EM) signal over the conducting polarizable ground on the measuring lines located on the axis of the source and inside it (for the symmetric Schlumberger installation). The research is based on a numerical experiment. Calculations of the EM response from one-dimensional models were carried out. The polarizability is taken into account by the frequency-dependent resistivity, using the Cole-Cole model. We describe the results of a numerical experiment on calculation of the induction signal over a conductive polarizable medium on grounded 2- and 3-electrode measuring lines located in the axial and equatorial zones of the source. It is shown that the induced polarization and the polarization associated with galvanic and eddy current are manifested in different ways.
