... Summary The theory of full-waveform inversion developed by Tarantola (1988) included inversion for the source wavelet. Source-wavelet inversion has been performed in the time domain by Zhou et al. (1997) and in the frequency domain by Pratt (1999). Minkoff and Symes (1997) performed...

... ABSTRACT We propose a 3D deblending method for towed-streamer simultaneous source data based on an L1 inversion algorithm. The approach pursues a sparse representation of 3D coherent signals that matches the blended data in a domain combining 2D TauP and 2D directional wavelet transforms...

Paper presented at the 2014 SEG Annual Meeting, October 26–31, 2014
Paper Number: SEG-2014-1632
... Summary In full-waveform inversion (FWI), a small disturbance in the source wavelet may lead to large discrepancies in the inverted model, which becomes larger as the depth increases due to error accumulation. Hence, accurate source wavelet estimation becomes crucial in a successful inversion...

In this paper we present an inversion methodology to extract a source wavelet from a prestack gather. This inversion estimates and deconvolves the effective source contribution...

... is difficult to guarantee in practice. In particular, when source wavelets for the two data sets are different, DDWI outputs are seriously impacted. To address this problem, we propose a double-wavelet double-difference time-lapse waveform inversion method (DWDDWI). This works because the data difference...

... at the same time in order to reduce the computational cost (equivalent to FWI). Although the velocity update is indepen- dent of the source wavelet, we can still update the source wavelet with Equation 4 in order to have benifits in source imaging. The whole inversion uses a nested approach, i.e. 1. inverting...
