- W2040996833 abstract "Removing ghost energy in marine streamer data is important for both seismic processing and interpretation. Full azimuth data have abundant azimuths, which require more robust 3D deghosting techniques. The coarse and irregular crossline sampling in full azimuth (FAZ) seismic data creates challenges for 3D deghosting. A fully data-driven 3D deghosting technique using a progressive sparse Tau-P inversion has proven to be able to overcome the sparse sampling in the crossline direction and to be effective in attenuating the receiver ghost in a 3D mode. We demonstrate the benefits of 3D deghosting using a staggered FAZ and ultra-long offset data set from Keathley Canyon, Gulf of Mexico. Using the data-driven 3D deghosting method, we observed less residual ghost energy in shot gathers from a side-gun when compared with the 2D pre-migration bootstrap deghosting method. The 3D deghosting method subsequently improved the images of steeply-dipping top of salt (TOS) and provided more coherent common imaging gathers." @default.
