A method of reducing effects of a rough sea surface on seismic data

摘要

A method of correcting seismic data for the effects of a rough sea surface is disclosed. Corrections for the effect of a rough sea surface are made by determining the time-dependent height of the sea surface, either by direct measurement or by calculation from the seismic data. A deconvolution operator is generated from the measured or calculated height of the sea surface and is used to reduce or eliminate the effects of the rough sea surface. Once the data has been corrected for the effect of the rough sea surface, it can be processed in any way suitable for processing seismic data obtained in flat sea conditions.
