Inversion of induced polarization effect using cole cole and gemtip models

  • 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


Inversion of induced polarization effect using cole cole and gemtip models

Cole-Cole model


Gemtip model

GEMTIP model

  • Geometric factors

    • Grain shape

    • Grain eccentricity

    • Grain size

    • Fraction volume % (porosity)

    • Grain alignment (anisotropy)

  • Reservoir parameters

    • Matrix resistivity

    • Grain resistivity

    • Grain polarizability

Inversion

The goal of inversion is to determine parameters from the

observed complex resistivity data
