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
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
