Broadband Processing of Conventional and Deep Tow Marine Streamer Seismic Data

Abstract

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 review two case studies of WiBand processing. In the first case study, data with streamers towed at different depths is used. 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. We conclude from the results that WiBand correctly removes the ghosts and recovers broadband data from deep tow streamer data. In the second case study, we compare inversion results from conventional processing and WiBand processing, and observe improved correlation with well logs.
