Salinity values in the Heletz Formation calculated by each of these methods were similar, and very close to the measured values obtained from chemical analysis of sampled schlumberger log interpretation charts water. Groundwater salinity in deep formations containing saline fluids can be estimated using SP logs. Under these circumstances, the modified Smits model offers no advantage over the traditional method.
Formation-water resistivity was calculated using both the traditional and the modified Smits models. For more information, visit the cookies page.

The modified approach takes into account effects of the clay mineral content and its electrochemical features on the electrochemical potential. In this study we adopted and modified Smits’ model for schlumberger log interpretation charts interpretation of groundwater conductivity which can be correlated with salinity.
schlumberger log interpretation charts Whereas Smits’ theoretical model was tested under laboratory conditions, its validity under field conditions was never established. We assume that the reason is that interpretattion these formations the shale acts as a perfect membrane.
Abstract Groundwater salinity in deep formations containing saline fluids can be estimated using SP logs.
Cores sampled from each formation were analysed for minerals as well as for cation exchange capacity, porosity and bulk density. Values calculated by each method in the Gevanim Formation were also similar, but lower than the measured value.
Findings in the two different formations suggest that the modified Smits model does not provide the log interpreter with a more accurate analytical tool. Recommended shlumberger Citing articles 0.
We tested this model in four deep boreholes, penetrating the Gevanim Anisian and the Heletz Neocomian formations in Israel. However, values of groundwater salinity calculated using traditional schlumberger log interpretation charts often deviate from measured values of sampled groundwater.
These parameters were later incorporated into the modified Smits equations.
