Description
The development of resistivity surveying techniques has been very rapid in the last three decades. The
advent of automated data acquisition systems, inversion codes, and easy access to powerful and fast
computers has tremendously increased the practical applicability of the geophysical method.
Geoelectrical resistivity imaging is increasingly being used in environmental, engineering and
hydrological investigations as well as geothermal and mineral prospecting, where detailed knowledge
of the subsurface is sought. In this paper, the historical development and basic principles of
geoelectrical resistivity surveying techniques are presented. Past researches and on-going
developments in the survey designs and field procedures in two-dimensional (2D) and threedimensional
(3D) geoelectrical resistivity surveys are discussed. Current development in the
acquisition geometry for 3D geoelectrical resistivity imaging data is emphasized
