Effective multidimensional resistivity inversion using finite-element techniques

Abstract:

This paper describes the development of a multidimensional resistivity inversion method that is validated using two-and three-dimensional synthetic pole-pole data. We use a finite-element basis to represent both the electric potentials of each source problem and the conductivities describing the model. A least-squares method is used to solve the inverse problem. Using a least-squares method rather than a lower-order method such as non-linear conjugate gradients, has the advantage that quadrat...
