Abstract
A best fitting trace in seismic data is determined for a desired trace to be reconstructed. A dip-based correction is calculated per trace and per sample for differences in azimuth, common midpoint coordinates, and offset between the best fitting trace and the desired trace. The dip-based correction is applied to the best fitting trace to reconstruct the desired trace for 3D surface-related multiple prediction.
Claims15
A method for marine seismic data reconstruction for 3D surface-related multiple prediction using a programmable computer that is programmed to perform the following:
- determining a best fitting trace in the seismic data for a desired trace to be reconstructed;
- calculating a dip-based correction per sample for differences in azimuth, common midpoint coordinates, and offset between the best fitting trace and the desired trace;
- and
- applying the dip-based correction to the best fitting trace to reconstruct the desired trace for 3D surface-related multiple prediction.
