Abstract
P001 Characterization of oil pollution by spectral induced polarization (SIP) Summary: 1 Oil pollution due to leakage from an underground supply network has been characterized using spectral induced polarization (SIP) imaging. Profiles at two different locations (contaminated and uncontaminated) have been imaged with different frequencies. The profile at the contaminated site clearly showed the phase and the resistivity highs at the contaminated horizon. The image of the phase highs was found best at a frequency of 3 Hz. Similarly the model obtained in the uncontaminated area (?) found a possible spot of contamination by the phase angle inversion whereas it
