Multi survey matching of marine towed streamer data using a broadband workflow: a shallow water offshore Gabon case study

Abstract

The presence of source and receiver ghost notches limit the useable bandwidth of marine towed-streamer data. In multisurvey processing, different acquisition configurations (i.e., variable source and receiver tow depths) can lead to variability in the notch period between the surveys. This complicates survey matching. Here we use source and receiver deghosting as part of a workflow to aid the matching of surveys with differing source and receiver tow depths. The data is from offshore Gabon.
