Multi-parameter FWI for structural imaging, amplitude fidelity, and reservoir properties

In the last few years, there has been an increased interest for multi-parameter Full Waveform Inversion (MP-FWI) in the seismic industry. In this paper we will revisit the motivation for this approach and show examples of what MP-FWI can offer compared to traditional FWI. Furthermore, we will discuss the key building blocks that should be considered to ensure true parameter de-coupling and simultaneous inversion.
