Methods and systems for deghosting marine seismic data |
| abstract |
A method is provided for deghosting marine seismic data. Marine seismic data is provided. The marine seismic data has a total acoustic wavefield that includes an upgoing acoustic wavefield and a downgoing acoustic wavefield. A deghosting operation to determine a part of the total acoustic wavefield corresponding to one of the upgoing acoustic wavefield and the downgoing acoustic wavefield is performed. The deghosting operation accounts for a varying vertical distance between a detector of a streamer and a sea surface. One of the upgoing and downgoing acoustic wavefields in the total acoustic wavefield is identified based on a result of the deghosting operation. The downgoing acoustic wavefield is removed from the total acoustic wavefield. |
