<p>DEVICE AND METHOD FOR DEGHOSTING VARIABLE DEPTH STREAMER DATAComputing device, computer instructions and method for deghosting seismic data related to a subsurface of a body of water. The method includes receiving seismic data recorded by seismic receivers that are towed by a vessel, wherein the seismic data is recorded in a time-space domain and the seismic receivers are located at different depths (Zr) in the body of water; modeling the seismic data in a shot or common midpoint domain as a function of linear operators that re-ghost the receiver to derive a model; using the derived model to remove the receiver ghost from the seismic data to obtain deghosted seismic data; and generating a final image of the subsurface based on the deghosted seismic data.Fig. 5</p> |
