Ghost Effect Analysis and Bootstrap Deghosting Application on Marine Streamer Data

Demand for broadband seismic data is rising. In this paper, we analyze the effect of the source and receiver ghosts on the wavelet, spectrum, and AVA. We also demonstrate how the bandwidth of constant-depth streamer data can be broadened with a bootstrap deghosting approach in the pre-migration stage. We use two constant-depth streamer examples from the Gulf of Mexico to show the benefits of bootstrap deghosting on restoring the bandwidth and reducing side lobes.
