Improved seismic envelope full-waveform inversion

Geophysics, 2023
ABSTRACT The envelope full-waveform-inversion method has the potential to greatly improve the estimation of long-wavelength components of subsurface seismic velocity, and simultaneously avoid or reduce inversion cycle skipping, by fitting the envelopes of observed and modeled seismic waveform data, rather than fitting the waveforms ...

Seismic Waveform Inversion with Source Manipulation

82nd EAGE Annual Conference & Exhibition, 2021
Summary In recent decades, Full-waveform inversion (FWI) has suffered from the cycle-skipping issue, which we found can be mitigated by changing the source signature of the observed data. Compared with a physical source such as the Ricker source, seismic data with the Gaussian source can provide a better landscape of the objective function while ...
