“…The important step in VES method improvement is petrophysical interpretation of soil resistivity. This technology was developed by A. Ryjov (Ryjov, 1987;Ryjov and Sudoplatov, 1990) and then applied in Mexico at more than 12 sites with oil contamination (Ryjov and Shevnin, 2002;Shevnin et al, 2004;2005a, b;2006). The forward petrophysical problem consists in the calculation of soil resistivity values on the base of PP of some soil model (mixture of sand and clay).…”

“…Thus, it is important to apply direct methods in every site to calibrate indirect methods. We can control the scatter in soil properties by sampling soil at every site and measure its resistivity versus pore water salinity to obtain soil model parameters from these data: clay content, soil, porosity of clay and sand and clay cation exchange capacity (Shevnin et al, 2004).…”

“…This information allows calculating correlation between filtration coefficients measured directly and estimated from clay content (Figure 7) for different types of formations (sand, till, silt, loam, mixture of sand and clay, kaolin and bentonite) with correlation coefficient 0.79. By means of the VES method, it is possible to estimate the filtration coefficient on base of clay content, found from soil resistivity and groundwater salinity (Shevnin et al, 2004). Finally, it is possible to calculate the hydraulic conductivity by the following steps:…”

“…Subsequently, a new methodology applied to environmental impact studies of the oil industry in Mexico (Delgado-Rodríguez et al, 2018) was developed, including geoelectrical survey and electrical measurements in soil and groundwater samples (Shevnin et al, 2006a, b). This methodology, using Ryjov's algorithm, resulted in the mapping of the aforementioned petrophysical parameters for accurate delineation of the hydrocarbon contamination plumes (Shevnin et al, 2004).…”
