The empirical coefficients are compared with Roy’s theory of ‘depth of investigation characteristic,’ and support that theory, if a modified definition of ‘effective depth’ is accepted.

By considering the theoretical results for simple earth models, a unique set of relative depth coefficients is empirically derived, such that measurements with different array parameters will ‘mesh’ smoothly into a combined pseudosection. Dipole-dipole induced-polarization measurements are commonly presented as pseudosections, but results using different gesistivity lengths cannot be combined into a single pseudosection.

The effective depths for various arrays are compared; the results agree with the traditional applications of each array. Application of these coefficients to a number of theoretical and field cases shows that they give reasonable results when applied to more complicated models.
