In this work, the results from the application of the VES method in the characterization of an oil contaminated site are presented. Electrical measurements in groundwater samples and petrophysical modeling helped to define the geoelectrical boundary between contaminated and clean zones. Highly contaminated zones are associated with the presence of free-phase hydrocarbons. By using contamination plume and limestone thickness maps some recovering drill holes were proposed for the remediation of the site by extraction of free-phase hydrocarbons.]]></p></abstract>

En este trabajo se presentan los resultados de la aplicación del método SEV en la caracterización de un sitio contaminado por hidrocarburos. Las mediciones eléctricas en muestras de agua y la modelación petrofísica ayudaron a definir la frontera geoeléctrica entre zonas contaminadas y no-contaminadas. Las zonas con máxima contaminación están asociadas con la presencia de hidrocarburos en fase libre en el subsuelo. A partir de los mapas de plumas de contaminación y del espesor de las rocas calizas, se proponen varios pozos de recuperación de hidrocarburos en fase libre para la remediación del sitio.]]></p></abstract>
