Summary Marine CSEM data processing techniques have evolved rapidly to accommodate the proliferation of marine controlled-source electromagnetic (CSEM) surveys. Processing methods developed for marine MT surveys are not directly applicable to marine CSEM data. Basic marine CSEM data processing eliminates the signature of the acquisition system and extracts the normalized spectral response of the earth from the receiver time series data. More sophisticated methods have been developed to simplify interpretation and to ensure that the highestquality data are available for inversion. These methods include determining the 3D receiver orientations by inversion, extending the range of useful offsets by noise suppression, and minimizing the effect of air waves by model-based subtraction. |
