In this work, the results of the geoelectrical characterization of a contaminated site caused by pipeline leakageare presented. Geoelectrical study was performed with multi-electrode technology and 2D profile data interpretation. VESresults from six parallel profiles were presented in resistivity sections and maps. Layered model of the site was found includingaquifer and aquitard layers. Although the contamination grade of the site is low, we found two contaminated zones into sandyaquifer. Aquifer and aquitard were characterized by its resistivity, clay content, porosity and cation exchange capacity values.Recalculation of resistivity data into petrophysical sections and maps was performed by an inversion algorithm taking intoaccount pore water salinity. Petrophysical parameters for uncontaminated areas estimated from resistivity are close to realvalues; meanwhile, in contaminated zones petrophysical parameters have anomalous values. Similar effects of contaminationinfluence on petrophysical parameters were found in laboratory by resistivity measurements made at clean and contaminatedsand samples. 2006 artículo científico 0016-7169 https://www.redalyc.org/articulo.oa?id=56845104 en http://www.redalyc.org/revista.oa?id=568 Geofísica Internacional application/pdf Universidad Nacional Autónoma de México Geofísica Internacional (México) Num.1 Vol.45 |
