VES data wereadded by water resistivity measurements and soil resistivity analysis. The contaminated zones feature with low resistivity anomaliessituated above groundwater level. The geoelectrical interpretation was compared with geochemical sampling. An inversecorrelation between electrical resistivity and concentration of contaminants confirms that the oil-contamination is mature and forthis reason it creates low resistivity anomalies. Petrophysical modelling allowed estimating boundary resistivity value separatingclean and contaminated zones. Resistivity data were visualized as cross-sections and maps and also were recalculated into sectionsand maps of petrophysical parameters, useful for more precise and detailed characterization of contaminated zones. 2005 artículo científico 0016-7169 https://www.redalyc.org/articulo.oa?id=56844304 en http://www.redalyc.org/revista.oa?id=568 Geofísica Internacional application/pdf Universidad Nacional Autónoma de México Geofísica Internacional (México) Num.3 Vol.44 |
