Abstract

An improved method, apparatus and article of manufacture are disclosed for modelling the response of induction logging and other electromagnetic tools to subsurface formations. The improvement of the computer-implemented method is determined by an improved 3D solution of the 3D Maxwell equations, including the following steps: (i) formulating a set of frequency-domain Maxwell equations, including a Maxwell operator; (ii) generating a Krylov subspace from inverse powers of the Maxwell operator, and (iii) repeating (ii) as needed to achieve convergence of a frequency domain solution.
