“…Given the strong dependence of chargeability on salinity equation (28), M t is a less important parameter for estimating permeability from SIP response, and so we do not compute f Q in our study. Nevertheless, the dependence of the partition coefficient on pH, as well as on ion and mineral species, might explain the nonunique behavior of the dependence of M t on temperature as reported in published studies [e.g., Vinegar and Waxman, 1984;Worthington and Collar, 1984].…”

“…Because of the CPA behavior, this means an increase or, respectively, a decrease of chargeability. However, Worthington and Collar [1984] refer in their review article to studies that report an increase in chargeability with temperature also for shaly sands. As far as we know, there is only one published study that deals with the dependence of relaxation time on temperature.…”

[1] The possibility to estimate permeability from the electrical spectral induced polarization (SIP) response might be the most important benefit offered by SIP measurements. It can thus be deduced that, in the future, SIP measurements will be carried out more frequently at the field scale or in a well-logging context to estimate permeability. In the shallow subsurface, however, the temperature generally exhibits seasonal variability, and in the deeper subsurface, it usually increases with depth. Hence, knowledge about the dependence of the SIP response on temperature is necessary in order to avoid possible misinterpretation of datasets impacted by thermal effects. In our study, we present a semiempirical framework to describe the temperature dependence of the SIP response. We briefly introduce the SIP response and its relation to permeability in terms of an electrochemical polarization mechanism and combine this formulation with relationships for the dependence of ionic mobility on temperature. We compare the predictions of our formulation with the experimental data from SIP measurements performed on sandstone at temperatures from 0°C to 80°C. The measured SIP response was transformed into a relaxation time distribution, using the empirical Cole-Cole model and a regularized Debye decomposition procedure. The SIP response was found to be in good agreement with the theoretical model. The temperature dependence of both direct current conductivity and relaxation time is controlled mainly by the dependence of ionic mobility on temperature, and the shape of the relaxation time distribution of the investigated sandstone is almost independent of temperature. The temperature effect on the SIP response can therefore be easily corrected.Citation: Zisser, N., A. Kemna, and G.

“…To better understand the mechanisms causing polarization and to extend the range of SIP applications to the vadose zone, it is important to investigate how the SIP response is affected by water saturation. Several studies have investigated the SIP response of unsaturated consolidated (e.g., Vinegar and Waxman 1984; Worthington and Collar 1984; Binley et al . 2005; Jougnot et al .…”

Electrical spectral induced polarization (SIP) measurements are increasingly being used in environmental studies of the saturated zone. To better understand the mechanisms causing polarization and to extend the range of SIP applications to the vadose zone, it is important to investigate how the SIP response is affected by water saturation. Therefore, sand and sand‐clay mixtures were drained in several steps using a novel measurement set‐up allowing SIP measurements with a high accuracy. The measured SIP spectra were interpreted by Debye decomposition, which provided a relaxation time distribution and a chargeability distribution that was converted to a normalized total chargeability. The results showed that the normalized total chargeability of the fully saturated samples increased with increasing clay content due to the larger specific surface area of the clay minerals. Furthermore, normalized total chargeability first increased and then decreased with decreasing saturation for the pure sand and the 5% sand‐clay mixture. The normalized total chargeability values for the 10% and 20% sand‐clay mixtures only decreased with saturation. The peak relaxation time of the sand‐clay mixtures clearly decreased with decreasing saturation. Existing grain‐size based mechanistic models for SIP are not able to explain the observed behaviour and the observed relationship between relaxation time and saturation suggests that model concepts relying on polarization processes in the pore space are warranted to explain the measurements on variably saturated porous media presented here.

“…Although IP also received widespread attention of geophysicists (Dakhnov, 1962;Loeb, 1976;Marshall and Madden, 1959;Vacquier et al, 1957) aiming at strengthening the physical understanding of the method yet, it could not get strength as a viable method except in the case of sulfide minerals. However, it is to be noted that for shaly sand formations IP has great potential for complementary/supplementary information in association with resistivity method for interpretation of subsurface configuration (Börner et al, 1996;Lima and Sri Niwas, 2000;Worthington and Collar, 1984).…”
