Report: Resistivity measurements before and after injection Test 5 at Raft River KGRA, Idaho. Final report

Abstract
Resistivity measurements were made prior to, and after an injection test at Raft River KGRA, Idaho. The objectives of the resistivity measurements were to determine if measureable changes could be observed and whether they could be used to infer the direction of fluid flow. Most of the apparent resistivity changes observed after the injection phase of Test 5 are smaller than the estimated standard deviation of the measurements. However, the contour map of the changes suggest an anomalous trend to the northeast which is similar to the trend in the self-potential data. The numerical modeling of the resistivity data is marginal for changes as small as those observed but the results suggest that changes of a few percent could be expected from a fracture zone extending from depth to within 100 m of the surface.
