ABSTRACT:
The present invention provides a method and apparatus for wave field separation. The method includes determining a first operator using marine seismic data acquired at a first depth and receivers deployed at a second depth, determining a second operator using marine seismic data acquired at a second depth, wherein the second depth is greater than the first depth, and forming a de-ghosted data set from the marine seismic data set based upon the first and second operators.
