Development of Multi-source Resistivity Profiling Using CDMA, Part.3, Evaluation by a Field Test

Abstract Field tests are conducted to study feasibility of the multi-source resistivity method using CDMA. As the results, we found that, 1.Effect of common current return is negligible, 2.Repeatability is better than conventional method, 3.Current waveform should be square or commutated DC, 4.Difference between the multi-source from the single-source is about as small as 0.2%
