f Detecting lateral resistivity inhomogeneities with the Schlumberger array

The Geological Survey of Norway has developed a method for recognizing lateral resistivity inhomogeneities with the Schlumberger cable (Ronning and Tønnesen 1990). The equipment used is constructed at the Geological Survey of Norway and consists of a multicore cable system. In this system the current and potential electrodes are connected to separate cables in order to avoid current leakage in the connections and cables.
