BP has been acquiring Multi-Azimuth (MAZ) Streamer Seismic in the Nile Delta since 2003. The initial results showed that MAZ data greatly improves general image quality, signal-to-noise ratio and lateral resolution, and suppresses diffracted multiples effectively. E-Lecture part 1 discusses the reasons why MAZ was selected and discusses the first results after time processing and PSTM imaging. E-Lecture part 2 discusses the workflow that combines the MAZ data in a multi-parameter reflection tomography approach to build a detailed velocity model that shows variations which correspond very well to the geology interpreted from the seismic, and which yields improved PSDM images. The results and learnings from both presentations are relevant and applicable to wide-azimuth acquisition and processing in general.
