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