SUMMARYAn important concern for time-lapse studies using the controlled-source electromagnetic (CSEM) method is repeatability of acquisition parameters for the base and monitoring surveys. We consider a challenging case when variations in source and

S U M M A R Y We present a rigorous method for interpolation of electric and magnetic fields close to an interface with a conductivity contrast. The method takes into account not only a well-known discontinuity in the normal electric field, but also

We have developed an efficient numerical scheme for fast multimodel 3D electromagnetic simulations by applying a Schur complement approach to a frequency-domain finite-difference method. The scheme is based on direct solvers and developed with constr

This abstract reviews the latest methods to optimize marine controlled-source electromagnetic (CSEM) data acquisition to ensure reliable interpretation in the presence of complex bathymetry. We specifically analyze how amplitude and phase of the reco
