Another possible development for VES method isestimating petrophysical parameters (PP) from RI data, using the relationship between electrical resistivity and PP. In order toreach this purpose, the theory of the forward and inverse problem that relates the electrical resistivity with PP was developed.Each field survey should include a VES (RI) survey, groundwater resistivity measurements in order to determine the groundwatersalinity, and collecting some representative soil samples in the study site for resistivity measurements as function of pore watersalinity in laboratory, creating a soil petrophysical model of the site. This technology can be used for the characterization ofuncontaminated and oil contaminated sites. For the case of contaminated site PP values determined in laboratory, groundwatersalinity and RI data help to define the petrophysical boundary between contaminated and uncontaminated soil, and consequently,to obtain the contamination plume. In this work, the results of the application of this technology in some hydrocarbon contaminatedsites in Mexico are presented. 2006 artículo científico 0016-7169 https://www.redalyc.org/articulo.oa?id=56845303 en http://www.redalyc.org/revista.oa?id=568 Geofísica Internacional application/pdf Universidad Nacional Autónoma de México Geofísica Internacional (México) Num.3 Vol.45 |
