ABSTRACT Learnings drawn from a large body of prior work should leave little doubt that broadband acquisition/processing add value to the seismic end product. However, there is still a lack of true 1-to-1 comparisons between processing-only versus acquisition-assisted methods. Here, we compare two-component (2C) deghosting with hydrophone-only (1C) deghosting, using seismic data acquired with a multi-component streamer system. We find that 2C deghosting provides a measureable uplift over 1C deghosting on migrated full-angle stacks, for both internally and externally processed data. This result validates multi-component streamers with regard to the method discussed here, i.e. 2C deghosting; however since the overall uplift is modest it may not translate into added value in the final product depending on survey objectives and target depth, amongst others. This needs to be evaluated on a case-by-case basis.
