Standard resistivity configurations lose resolution in regions where multiple geologic layering of high conductivity contrast occurs. To partially circumvent this problem an electrode configuration was used, which includes a current electrode at depth down a drill hole in a water field, to examine the possibility of delineating ground‐water flow channels. Results show the value of this technique in enhancing the electrical anomaly and hence determining structure. It was found that the ground water in this area flows primarily in fracture traces in the dolomite. Moreover, it was determined from well log synthesis that these fracture traces increase the effective porosity in the flow region by approximately ten percent.
