Influence of induced polarization in inductive methods

Abstract

This paper considers the influence of induced polarization (I.P.) on frequency and transient responses for three configurations used in the inductive methods of electroprospecting. Special attention is paid to the influence caused by the presence of relatively conductive inhomogeneities and to various approaches allowing one to separate the inductive effect from the induced polarization.

It is shown that the quadrature component is less sensitive to the I.P. effect than the inphase component. Also the transient field at the late stage is strongly affected by induced polarization. It is also shown that the dipole-dipole array is least sensitive to the I.P. effect.
