Reconstruction of Wide Azimuth Seismic Data: Assumptions, Methodology And Field Examples

The Minimum Weighted Norm Interpolation (MWNI) algorithm (Liu and Sacchi, 2004, Trad et al. 2005) has been proposed as a method to reconstruct band-limited seismic data that depends on 1, 2, 3 and 4 spatial dimensions. In addition, Sacchi and Liu (2005) and Hunt et. al (2008) have demonstrated the ability of the method to reconstruct the data prior to true amplitude migration. Recently, Trad (2009) provided a full description of the method and its application to 5D seismic data regularization. That work emphasizes the realistic industrial strength of the method for seismic data processing flows.
