Paper presented at the SEG International Exposition and Annual Meeting, October 11–16, 2020
Paper Number: SEG-2020-3426347
... series is only guaranteed to converge if the contrasts and the size of the model (relative to the wavelength) are relatively small. In this study, we have used the so-called homotopy analysis method to derive an iterative method of the Lippmann-Schwinger equation which is guaranteed to converge...

Paper Number: SEG-2016-13763783
... presents a new 3D curvature attribute analysis method with an excellent anti-noise property. Firstly, continuous wavelet transform is used to extract phase-cosine attribute from seismic data. Then apparent dips are calculated based on complex seismic theory and filtered using median filter. Finally, many...

Paper presented at the 2015 SEG Annual Meeting, October 18–23, 2015
Paper Number: SEG-2015-5843824
... Summary One important application of time frequency analysis is the identification of channel complex. However, conventional time frequency analysis methods suffer from low resolution which sometimes leads to relative terrible interpretation results. In this paper, a novel time frequency...
