Three-dimensional geoelectrical imaging of the subsurface structure of university of Benin-Edo state Nigeria

Owens Monday Alile and Ema Michael Abraham

We use 2D and 3D resistivity imaging techniques to produce images of the subsurface structure of the capitol gate area of the University of Benin, Edo State Nigeria. 2D and 3D resistivity imaging methods are simple, fast, inexpensive, and relatively accurate techniques used in geophysical exploration. Orthogonal set of 2D geoelectrical resistivity field data were collected using the conventional Wenner array configuration. The observed 2D apparent resistivity data were processed into 3D data set using a 3D inversion code. The 3D model resistivity images obtained from the inversion are presented in horizontal and vertical depth slices and block images. This study has shown the effectiveness of 3D geoelectrical resistivity imaging using parallel 2D profiles
