WebWe have developed a novel data-assimilated TLFWI method to construct high-resolution time-lapse velocity and attenuation changes from dense time-lapse monitoring data. This method consists of two theoretical developments: visco-acoustic full-waveform inversion (QFWI) and multiparameter hierarchical matrix-powered extended Kalman filter (mHiEKF).

WebThe well-proven Time-lag FWI (TLFWI) provides a leap in resolving the complex salt model and brings a step change to subsalt imaging. FWI Imaging leads to another step change in subsalt imaging by maximizing the illumination power of existing data through least-squares fitting of the full-wavefield data. WebTime-lapse acoustic/elastic full waveform inversion (TLFWI) algorithms are able to recover high spatial resolution statics subsurface velocity models by retrieving waveform information from time-lapse seismic data, but the neglecting attenuation caused by the injected CO 2 blurs the final velocity models. Another question is the TLFWI methods ...
