... are updated simultaneously. The algorithm is applied to multicomponent reflection data generated for a modified section of the BP TI model. The inversion significantly reduces the data misfit and recovers the long-wavelength components of the attenuation parameters, especially in the upper part of the...

... computes attenuation parameters Q by extracting transient seismic waves in prestack domain. Firstly, the initial wavelet model is given. Then the four order cumulative quantity matching method is used to estimate the wavelet spectrum from the amplitude spectrum of the seismic record, and the optimal Q...
