![]() (2001), but here in addition to improving results for dipole-dipole array, its productivity is demonstrated for other geo-electrical arrays such as Wenner alfa, Wenner Schlumberger. The presented technique was used only for dipole-dipole array by Perez-Flores et al. Inversion algorithm is iterative and regularization parameter and depth weighting exponent are the critical parameters that have default values of 0.1 and 1, respectively. We took the advantage of the 2-D forward operator formula obtained based on integral equations (IE) by Perez- Flores et al. Inversion procedure is linear however, DC resistivity data inversion is generally nonlinear due to the nonlinearity of Maxwell’s equation relative to resistivity (conductivity). In this paper, a new simple, efficient and semi-automatic algorithm including depth weighting constraint is introduced for 2-D DC resistivity data inversion. ![]()
