Abstract
2D and 3D resistivity imaging methods are simple, fast, inexpensive, and relatively accurate techniques used in geophysical exploration. In this study, 2D and 3D resistivity imaging methods were used to produce images of the subsurface structure of the capitol gate area of the University of Benin, Edo state Nigeria where orthogonal set of 2D geoelectrical resistivity field data were collected using the conventional Wenner array configuration. The observed 2D apparent resistivity data were processed and then collated into 3D data set which was processed using a 3D inversion code. The 3D model resistivity images obtained from the inversion are presented in horizontal and vertical depth slices in contour and block images. This study was carried out to show the effectiveness of 3D geoelectrical resistivity imaging using parallel 2D profiles.
