Abstract
Systems and methods for deghosting seismic data using migration of sparse arrays are disclosed. The methods may include obtaining input seismic data, the input seismic data including a first set of seismic data recorded by a first set of seismic receivers located at a first depth, and a second set of seismic data recorded by a second set of seismic receivers located at a second depth. The method may further include migrating the first set of seismic data to an image grid, and migrating the second set of seismic data to the image grid. Additionally, the method may further include calculating a ghost wave based on the first and second sets of migrated seismic data, and deghosting the first set of migrated seismic data by removing the ghost wave.
