The geophysics we describe here will sound different from what you have heard before, because it is different. It uses electric fields instead of seismic waves. It is not designed for exploration. It is a distant cousin of cross borehole seismic tomography, although it is quite different in terms of its application and results. Probably the most curious aspect is that it doesn't chase the holy grail of geophysics—high resolution.

What good could possibly come from a low-resolution, electrical geophysical tool? The answer is found in the paradigm gradually finding favor by oil executives and reservoir engineers: while finding and...
