Editor's note: This paper is a condensation of a review titled “Electrical resistance tomography—Theory and practice,” to be published in Near Surface Geophysics, vol. 2, D. Butler, ed., by SEG in 2004. See page 472 for a case study on this topic.

Electrical resistance tomography (ERT) is a method that calculates the subsurface distribution of electrical resistivity from a large number of resistance measurements made from electrodes. For in-situ applications, ERT uses electrodes on the ground surface or in boreholes. It is a relatively new imaging tool in geophysics. The basic concept was first described by Lytle and Dines as...
