Induced polarization (IP) method is part of the geoelectric methods that is often used in metal exploration. Data interpretation from induced polarization survey requires a fast and efficient forward modeling algorithm. In this study, a forward modeling of induced polarization scheme for 2D environment was developed. The finite element method (FEM) was used for calculating the IP responses for a 2D subsurface resistivity model. The FEM was implemented in the scheme by using the Galerkin approach. The modeling scenarios were divided into two: the first is a case where the subsurface was a homogeneous resistivity whereas the values of injected current were varied. The second case is where the subsurface posses two resistivity layers with a constant value at the injected current. The result show that at a constant current, the electric potential differences are proportional to the resistivity value. Whereas for the two-layers case, the increase in the potential difference is proportional to the increase in resistivity and that current penetrates deeper in the resistive layer.
