1. Inversion of Induced Polarization Effect Using Cole-Cole and GEMTIP Models Haiyan Fu 12/13/2011

2. Studying of the IP effect is important for developing the methods of subsurface geophysical exploration Modeling the IP effect can lead to accurate mineral discrimination

3. Cole-Cole model

4. GEMTIP model Geometric factors –Grain shape –Grain eccentricity –Grain size –Fraction volume % (porosity) –Grain alignment (anisotropy) Reservoir parameters –Matrix resistivity –Grain resistivity –Grain polarizability

5. CR The goal of inversion is to determine parameters from the observed complex resistivity data Inversion
