EAGE Workshop on Broadband Seismic
In marine acquisition both a direct wavefield and a ghost wavefield are produced as well as recorded. Hence, the seismic data can be considered to be a natural blend of four wavefields related to the real sources, ghost sources, real detectors and ghost detectors respectively. We consider deghosting to be deblending ('echo-deblending'), leading to a non-causal, full-wavefield algorithm, characterized by utilizing the ghost. Therefore, echo-deblending is different from prediction-error solutionsdoi:10.3997/2214-4609.201414425 fatcat:abq4c7d3f5h2dlnwohu6y4zf3m
