Abstract

Summary

Removal of the sea surface effects is an important step for subsurface imaging. In this abstract, we investigate source deghosting and demultiple considering time-varying rough sea surfaces. We derive, based on Rayleigh’s reciprocity theorem, integral equations for modelling the source ghost and surface related multiples from time-varying sea-surfaces. From the derived theory, we show that source deghosting fails in the presence of free-surface multiples. This observation is supported by synthetic data examples. However, if the time-varying sea surface interactions are solely in the input wavefields, the inversion is successful. Thus, by applying source deghosting and demultiple by integral inversion, all effects from the time-varying sea surface are removed in one step.
