In the last decade Petrobrás drilIed a great number of wells based on the presence of amplitude anomalies mostly bright spots in seismic data. Not all of these wells proved to be producers. This study aims to investigate whether the application of amplitude versus offset (AVO) or angle analysis techniques would have increased the success rate of drilling. A second aim of this study is to point out for what type of data AVO analysis is feasible and what suite of preprocessing is needed before the data are submitted to AVO analysis.
