Abstract

Summary

A 2D inversion algorithm for time domain induced polarization data has been developed. The IP transients are inverted into 2D Cole Cole models including resistivity, chargeability, relaxation time, and frequency constants. In order to speed up the inversion procedure, an approximate forward algorithm has been used which is highly accurate and its validity was tested with exact solutions up to 3D. In the 2D inversion procedure, a 3D DC forward algorithm has been used as forward operator. The method requires a conventional 2D DC inversion and a homogenous half space Cole-Cole inversion to derive the Cole Cole parameters of each cell. Synthetic model studies and a field example will be demonstrated.
