Petrophysical and Electrical Study of Soil Properties in Sinaloa, Mexico

SUMMARY In area of study near the channel Valle del Fuerte in Sinaloa state, Mexico, geological and geoelectrical characteristics of soil were measured in seven key areas. In each of seven key areas an electrical resistivity tomography (ERT) profile was fulfilled, three boreholes were made with soil samples collection in each borehole, filtration coefficients of soil, cation exchange capacity, porosity and grain size distribution, groundwater salinity and ionic content in water were determined. ERT data were interpreted and soil resistivity curves versus pore water salinity were measured. Joint analysis of all data obtained was performed to find correlations between them to create petrophysical model of soil. Verification of this model was performed by correlation between the same petrophysical parameters measured in laboratory and obtained from geophysical data.
