Improving reservoir geometry by integrating continuous wavelet transform seismic attributes

Summary Seis mic interpretation is highly dependent of the seismic resolution. Sequence stratigraphy, fractures detection, faults interpretation and channels delineation can be improved by using better resolution seismic data. Considering spectral decomposition a way increase seismic traces details, we used complex continuous wavelet transform (CWT) ridges to create a higher resolution traces and the CWT phase interferences, or residues, to detect subtle seismic discontinuities. By integrating these seismic attributes we showed how to improve the understanding of reservoir geometry. The technique was applied to real data and using calibration wells we confirmed the effectiveness of the proposed methodology.
