WebSep 17, 2012 · Inversion of seismic data plays a vital role in reservoir characterization. High-resolution inversion methods incorporate other information, like well-log data, to approach broad-band inversion results. FWI is an optimization process that seeks an Earth model, e.g., P-wave velocity, to best fit the waveform of seismic record in a sense of the norm defined in the objective function. The concept and framework of FWI were proposed by Tarantola ( 1984 ), who is a French professor in geophysics.
