Our results imply that measurements of the spontaneous potential at a production well will combine contributions from both streaming and electrochemical effects, and may be used to detect an advancing waterfront some time before water breakthrough occurs at the well. Moreover, inversion of the measured signals could be used to determine the water saturation in the vicinity of the well, and to regulate flow into the well using control valves in order to maintain or increase oil production.
