IOSC on State of the Art in Full Waveform Inversion (FWI) by Ian Jones

For the topics listed below, real data examples will be used to demon-
strate the application and limitation of each technique. 

• Why do we need a detailed velocity model? 

• Migration using wavefield extrapolation methods (WEM, RTM, etc.)
One-way versus two-way propagation

 • Resolving short-scale-length velocity anomalies 

• The mechanics of tomographic inversion with wavefield extrapola-
tion theory (FWI)
The scattering limit
Refraction versus reflection
 

Different ‘norms’ (dynamic versus kinematic: least-squares, travel
time, phase, optimal transport) 

• Examples of current industrial practice for various geological settings
