In recent years, wide-azimuth seismic data has been demanded by most of seismic interpreters. On the other hand, in marine environments, it is much common to have seismic acquisition performed using a vessel towing a number of streamers. Given the use of increased number of streamers by geophysical contractors in recent years, and the fact that the increase in the number of streamers has ended up, in some sense, will widen the azimuth coverage of the acquired seismic data, the perception that the acquisition of seismic data using higher number of streamers will provide wide-azimuth seismic data has been emerged. This study is an attempt to analyze this subject-matter and especially it focuses on the drawbacks associated with data acquisition using an excessive number of streamers in shallow waters such as Persian Gulf. The results indicate that, excessive number of streamers not only results in non-uniformity of bin indicators, but also creates geometry foot print and prevents recording of shallow reflections.
