| Abstract | IP measurements are one of the most important geophysical parameters, which unfortunately is quite difficult to analysis. In this research is containing with comparison of decay based on the variation of modes, injection time and how decay varies with the cement ratio changes. Additionally, Prediction of permeability based on geophysical measurements is currently one of the most challenging issues in geophysics. There have been recently reported some important relationships between permeability and induced polarization (IP) parameters for a different sample including cement admixed clay samples and natural soft clay. However, the disadvantage of this approach is the very scarcity of IP data as most of prac- tical measurements are time-domain IP. In this research, an innovative approach using re- sistivity and chargeability measurements to predict permeability of soft clay was proposed and successfully applied for tested samples based on measurements of resistivity and time domain IP data for different types of electrode configurations. Total number of 6 samples were made and tested for 28 days of curing process. The permeability predicted by resis- tivity and chargeability model in this research matched well with permeability measured by consolidation testing. |
