Broadband Processing of Conventional Marine Streamer Seismic Data

We have developed WiBand, a de-ghosting and broadband processing method that can be applied to conventional streamer data acquired with single component streamers. We recorded, over one sail line, multi-streamer data with the streamers towed at different depths, obtaining data over multiple subsurface lines (tracks) parallel to one another. We apply WiBand to each track independently to remove the effects of the source and receiver ghosts. We compare the WiBand results from a deep tow track to conventionally processed result from a shallow tow track to validate the phase fidelity of the de-ghosting process. The results lead us to conclude that WiBand correctly removes the ghosts and recovers broadband data from deep tow streamer data.
