ABSTRACT:
This invention provides a method for compensating for the deleterious effects of irregular spatial sampling of seismic data. The imbalance caused by sparse sampling is corrected by decomposing a processed data gather into its constituent dip and azimuth components, analyzing the movement and scaling of selected attributes of those components and applying an inverse sampling operator to the processed data based upon the analytical results.
