2-D Lamarckian Inversion of Resistivity Data

ELECTRICAL ELECTROMAGNETICS & GPR O10 - 03 2-D LAMARCKIAN INVERSION OF RESISTIVITY DATA Introduction Irfan Akca Ahmet T. Basokur Ankara University Turkey The purpose of the inversion algorithms is to derive the subsurface distribution of a certain type physical parameter that causes the variation of applied geophysical fields. The inversion of geophysical data is carried out by updating an initial guess supplied by the interpreter in an iterative manner. The most of inversion algorithms are based on the estimation of a new set of parameters that provides less misfit error than that of the previous iteration. The parameter change vector
