AB  - Full waveform seismic inversion, as currently commercially available in 3D, uses the acoustic approximation to the wave equation, and generally ignores the effects of elasticity, attenuation and anomalous density variations. We examine the consequences of these practical compromises by inverting 3D synthetic seismic data using different approximations to the physics of wave propagation in the forward and inverse modelling. We also invert using different portions of the data, and examine the effects of data amplitudes. We conclude that current FWI practice works well if amplitudes and reflected energy are suppressed in the inversion, but that a more-complete description of the physics is required in order to extract quantitative physical properties from amplitudes and reflections.
