  • Method for deghosting seismic data acquired by a marine seismic source and receiver assembly
    Patent number: 11209562
    Abstract: In a method for deghosting seismic data acquired by a marine seismic source and receiver assembly effects of seismic reflections by the water surface, known as ghost signals, are removed by a deghosting algorithm, which transforms input seismic data with the surface ghost reflections into source- and receiver-deghosted seismic data using a sparse-inversion technique both for hydrophone and/or geophone recordings, which technique includes equation (26), thereby considerably improving usuable bandwidth and giving rise to a significant imaging uplift.
