The term "full waveform inversion" (FWI) refers to a seismic imaging technique used in geophysics to reconstruct subsurface Earth models with high resolution. FWI is a full-physics method that aims to match observed seismic waveforms with synthetic waveforms generated from a subsurface model, adjusting the model iteratively to minimize the difference between the two. Unlike traditional reflection-based methods, FWI utilizes the entire seismic waveform, including both reflected and transmitted waves, to improve the accuracy of subsurface imaging.
The process begins with an initial Earth model, often derived from surface seismic data or well logs.
FWI is particularly valuable in complex geological environments where traditional methods may fail, such as in
