Paper Number: SEG-2020-3428440
... We find that a sparse-pulse decomposition of seismic images provides accurate means to estimate the seismic source waveform. The corresponding spectral character allows us to estimate the quality factor Q to quantify seismic attenuation using the spectral ratio method. Tests on seismic trace...

However, the best atom searched by multichannel matching pursuit currently is just shared by lateral seismic traces at the same time slicers. The lack of directionality in multi-channel search strategies leads to irrationality in dealing with the seismic...

... and computationally intensive least-square based approaches. Current time-frequency analysis algorithms are usually implemented on single seismic trace. As a result, the decomposed frequency components are strong affected by noise and lack of spatial continuity. Simultaneous processing multiple seismic traces...

... for the current methods. Instead of computing the dip and azimuth sample by sample, we propose to determine the dip and azimuth for all samples of a seismic trace simultaneously. We treat the dip and azimuth estimate as a global optimization problem and employ dynamic programing to obtain the dip and azimuth...

... seismic traces can be created including only reflection coefficients within certain amplitude ranges. Large inverted reflection coefficients can be removed and the residual reinverted, thereby stabilizing inversions for the remaining weak events. By this reflectivity decomposition, subtle impedance...

Each sinusoidal wave is regarded as a model component and is represented by a set of distinct parameters. Secondly, a novel...
