Full 3D Inversion of Marine CSEM and MT data on PCs

Abstract As marine CSEM methods have been increasingly used for hydrocarbon exploration in various complex settings, there is increasing interest in developing and applying 3D inversion methods. This paper presents a 3D inversion algorithm for marine CSEM and MT data that is implemented on PCs. It uses an efficient staggered-grid finite-difference method for the forward modeling and is based on the Gauss-Newton approach. A synthetic data example shows the effectiveness of the algorithm and the benefit of inverting CSEM and MT data.
