Quantification of acquisition uncertainties in seismic wavefield deghosting

Marine seismic acquisition is troubled with several factors of noise that can deteriorate seismic data. Marine seismic data are recorded with towed streamers that acquire the desired upgoing wavefields containing information of the geology beneath. The upgoing wavefield will travel past the streamer/hydrophone to be reflected at the sea surface...

Data-driven 3D Deghosting Using Multisensor Marine Measurements

Marine seismic acquisition tows submerged streamers to record pressure waves from the subsurface. The recording, however, contains both the desired upgoing wavefield and its (immediate) reflection off the sea-surface, causing a downgoing wavefield known as the seismic ghost. Interference between the up- and downgoing waves causes periodic low...

Adaptive deghosting of seismic data: A power-minimization approach

In marine seismic acquisitions, a major deteriorating effect on resolution is caused by ghost re- flections. Sensors towed at depth within a water column record not only the desired up-going wavefield reflected from geological formations, but also its reflections from the sea surface known as down-going wavefield, or seismic ghost. This...
