“…The results of the measurements in situ and of the laboratory tests at 15 groundwater samples (samples [20][21][22][23][24][25][26][27][28][29][30][31][32][33][34], presented maximum EC of 3.5 mS/cm, minimum EC of 2.1 mS/cm, and a mean value of 2.7 mS/cm corresponding to salinities of 2.1, 1.3, and 1.6 g/l, respectively, indicating the presence of slightly saline water. A similar number of soil samples from the aquifer were analyzed to determine its texture under the Bouyoucos technique.…”

Playa Las Glorias is the main tourist destination for the inhabitants of the municipality of Guasave, Sinaloa, México, and it overlies a shallow coastal aquifer. In recent years, the momentum of the tourism industry in the region has brought a growing demand in the consumption of drinking water. Because of this, it is relevant to the precise knowledge of the interface of slightly brackish saltwater for an efficient planning of new wells by the municipal authorities. For efficient groundwater exploitation, it was taken into consideration the productivity of the aquifer and the environmental impact that would cause improper management of water resources. The electromagnetic profiling (EMP) method was applied in Playa Las Glorias, Sinaloa, Mexico. A total of 150 measurements of EMP distributed in 11 profiles were performed, of which 10 were perpendicular to the coast and one parallel to it, using an EM34 meter in horizontal polarization and separation between coils of 10 m and 20 m. The apparent conductivity maps show an anomaly of low conductivity, indicating the presence of fresh or slightly saline water. In this anomalous zone we performed an electric resistivity tomography (ERT) profile to determine the behavior of groundwater salinity finding a shallow layer of freshwater, and as it deepens the salinity increases due to the influence of the sea. In addition, electrical resistivity (R w ) values were measured in groundwater samples that, along with the resistivity values (R o ) for sandy formation obtained from ERT data, allowed us to determine a lineal relationship between both resistivities. A hydro geochemical study was conducted in the site through Piper diagrams and Chadha, indicating a predominance in the region of chlorinated water due to the influence

Hydraulic conductivity is an important parameter, representing permeable property of the groundwater in aquifers, in the issues of groundwater development, groundwater contamination, and groundwater flow, etc. We estimated a relationship between hydraulic conductivity and electrical properties (formation factor, chargeability, and time constant) of silty sand in the laboratory. For this study, we conducted grain size analysis, constant head permeameter test, and measured electrical resistivity and spectral induced polarization of silty sand samples collected from the riverside alluvium of the Nakdong River in Nogok-ri area, Dasan-myeon, Goryeong-gun in Gyeongbook Province, Korea. In the laboratory test, we used soil samples of approximately uniform porosity with 0.5% error range, and kept the electrical resistivity of pore water with 100 ohm-m. As a result, the relationship between effective particle size and hydraulic conductivity agrees fairly well with the existing empirical formulas. Hydraulic conductivity was correlated with formation factor, chargeability, and time constant: hydraulic conductivity increased with increasing formation factor and time constant as well as with decreasing chargeability.

“…Similarly, for unconsolidated media there are also available data on the negative correlation between k and Ғ, of which we have selected those presented by Jones and Buford (1951), Kosinski and Kelly (1981), Urish (1981), Kelly and Frohlich (1985) and Huntley (1986). Figure 2 shows data extracted from these works, in which we have not taken into account the very shaly sandstone data of Waxman and Smits (1968) and the limestone data from Carothers (1968).…”

-The main objective of this study is to find a relationship between permeability and porosity, in the range 0 up to 50%, so that the permeability could be estimated only through geophysical parameters. This relationship should be consistent with the statistically expected values in sedimentary basins, and it should include the positive correlation between permeability and porosity in consolidated media and the negative correlation in unconsolidated ones. We have also developed another relationship between formation factor and permeability, considering that the values of porosity and pore fluid resistivity are known from other sources different from resistivity logs. -The method for determining these relationships has been to generate functions with the expected geometry and to fit them to empirical data drawn from published papers. As a result we obtained a new relationship between porosity and permeability, with cementation exponent as added variable, and a new relationship for indirect estimation of permeability from the formation factor. Given the formation factor dependence with clay content, we have also developed a theoretical relationship to calculate the formation factor in a clayey media, assuming that clay content is known from other logs. In this relationship, we have not taken into account the presence of non-conductive liquid phases, such as oil.Comparison of the results obtained from these expressions with data collected in the literature leads to conclude that it is possible to determine the permeability of each layer in any zone from resistivity logs, if both the clay content and the resistivity of the interstitial fluid are known.Résumé -Estimation géophysique de la perméabilité dans les milieux sédimentaires avec des porosités comprises entre 0 et 50 % -L'objectif principal de cette étude est de trouver une relation entre la perméabilité et la porosité dans la gamme de 0 à 50 %, de sorte que la perméabilité puisse être estimée seulement par des paramètres géophysiques. Cette relation doit être statistiquement compatible avec les valeurs attendues dans les bassins sédimentaires, et inclure la corrélation positive entre la perméabilité et la porosité dans les milieux consolidés et la corrélation négative dans ceux non consolidés. Nous avons également développé une autre relation entre le facteur de formation et la perméabilité, étant donné que les valeurs de la porosité et de la résistivité du fluide des pores sont connues de diverses sources autres que les diagraphies de résistivité. La méthode de détermination de ces relations a été générée en fonction de la géométrie attendue, et ajustée aux données empiriques des documents publiés. En conséquence, nous avons obtenu une nouvelle relation entre la porosité et la perméabilité, en utilisant l'exposant de cimentation comme une variable supplémentaire, et un nouveau rapport à l'estimation indirecte de la perméabilité à partir du facteur de formation. Compte tenu de la dépendance du facteur de formation avec la teneur en argile, nous avons ...
