Abstract The results of 3D inversion are analytically compared with the results of applying 2D inversion program to conducting inversion of 3D geological bodies in DC resistivity sounding. The methods for modeling and confirmation of prior information are compared, followed by a comparative analysis of several inversion examples of typical models. In 2D inversion, the precision of location, shape and resistivity is relatively low in that only single section information is taken into consideration. The results of 3D inversion are in good accord with the practical models because such an inversion has synthesized the information of several sections.
