WebbFör 1 timme sedan · Seismic imaging and inversion become extremely challenging when dealing with salt structures. Conventional state-of-the-art full-waveform inversion (FWI) fails to recover those features in areas where salt is present. A widely used solution in industry, however, involves substantial human interpretation. In this study, a regularized … Webb1 nov. 2024 · Complex seismic trace analysis is a fundamental tool for seismic attributes analysis (Barnes, 2006). Originally, it was discussed in electrical engineering and signal analysis literature (Gabor, 1946; Bracewell, 1986; Cramér and Leadbetter, 1967; Oppenheim and Schafer, 1975).
WebbThis is done through a process called binning, by dividing the 2D line range or the 3D survey area into a number of equal-sized CMP bins and, for each bin, collecting those traces whose midpoints fall within the bin as the CMP gather of this bin. The number of traces, or midpoints, within each CMP bin is called the fold. As an important seismic WebbThe ideas of 1-D complex seismic trace analysis extend readily to two dimensions.
