A two-layer situation is encountered often in electrical prospecting. two-layer cases were interpreted with the aid of characteristic curves.  These theoretical curves, calculated for a particular four-electrode array, take into account the change in depth penetration when current lines cross the boundary to a layer with differentresistivity. The electrical boundary conditions require continuity of the component of current density J normal to the interface and of the component of electric ...
