A bstract A lfano L. 1980, Dipole‐Dipole Deep Geodectric Soundings over Geological Structures, Geophysical Prospecting 28, 283–296. The dipole‐dipole array is used for deep vertical geoelectric soundings for practical reasons. However, the data obtained are often too scattered and the quality is lower than that of a Schlumberger sounding. The mathematical transform from these fields data to the corresponding Schlumberger ones is needed. It is demonstrated that for more general underground structures different from plane parallel stratifications, only the continuous polar dipole‐dipole array permits a general and reliable transform of this type. It follows that any other dipole‐dipole array, (for instance the azimuthal, equatorial, parallel, perpendicular, etc.), are useless over complex structures, or in the presence of irregularities on the ground surface.
