Abstract
A method for deghosting marine seismic streamer data includes receiving the marine seismic data recorded from a single streamer. A representation of an upgoing wavefield in the marine seismic data is defined. The representation of the upgoing wavefield includes a first wave component in a plane and a second wave component that is perpendicular to the plane. A linear system is built that models a wavefield using the representation. The wavefield includes the upgoing wavefield and a downgoing ghost wavefield. The upgoing wavefield is estimated, within the representation, by inverting the linear system.
