Three-Dimensional Interpretation of the Marine CSEM Data Using Joint Iterative Migration of Electric and Magnetic Fields

D039 Three-Dimensional Interpretation of the Marine CSEM Data Using Joint Iterative Migration of Electric and Magnetic Fields M.S. Zhdanov* (University of Utah) & T. Ueda (University of Utah) SUMMARY Marine controlled-source electromagnetic (MCSEM) surveys have become widely used in off-shore petroleum exploration. However the interpretation of the MCSEM data is a very challenging problem because of the enormous amount of computations required in the case of the multi-transmitter and multireceiver data acquisition systems used in these surveys. In this paper we demonstrate that this problem can be solved using the method of electromagnetic migration. We extend the basic principles of
