Abstract
A method for assessing data coverage in a three dimensional marine seismic survey includes determining at least one Fresnel zone for at least one of a plurality of seismic data traces. A contribution is determined for each of the seismic data traces to each one of a set of bins in a defined pattern. Each contribution is based on the Fresnel zone associated with each seismic data trace. The contributions from all seismic data traces contributing to each bin are summed. The summed contribution for each bin are stored or displayed and the summed contributions in each bin are compared to a selected threshold to determine coverage.
