Abstract :
Time-lapse marine Controlled Source Electromagnetics is capable of detecting changes in a subsurface reservoir. How ever, changes related to the source or the ocean affect the data much more than possible changes in a reservoir. We show that those unwanted effects can be largely suppressed by applying interferometry by multidimensional deconvolution. Two numerical examples illustrate that the resulting reflection response contains only effects related to the subsurface.
