Spectral induced polarization (SIP) technique is widely used in environmental and engineering geophysical prospecting, as well as mineral exploration, oil, gas and coal exploration. The SIP method can provide measurements of multifrequency complex apparent resistivity at ultra low frequencies,(10-2- 102 Hz), to determine spectral parameters and spatial distributions of buried geologic structures. Since the method measures complex apparent resistivities, it is also called the complex resistivity (CR) method. In the theory of SIP data interpretation, defined as the inversion of three spectral induced polarization parameters (m, and c), the main task in SIP technique is using the Cole- Cole model. This paper shows the application of SIP method to oil and gas exploration on the Dehdasht oil reservoir.
Results showed that the averages of the apparent SIP parameters in the anomalous section are useful for discriminating the source of the anomaly.
