Summary:
o) & H. Li (WesternGeco) SUMMARY 71 st EAGE Conference & Exhibition — Amsterdam The Netherlands 8 - 11 June 2009The past couple of years have seen a tremendous increase in the acquisition of wide azimuth (WAZ) surveys that provide improved subsalt imaging. We have seen a step change improvement in image quality compared to conventional narrow azimuth (NAZ) surveys even when using minimal processing and existing conventionalsurvey velocity models. The improvement in image quality is taken to the
