Full waveform inversion has emerged as the final and ultimate solution to the Earth resolution and imaging objective. It can potentially include the comprehensive computational simulation of the true field experiment, in which the observed data is reproduced using the inverted model of the subsurface. However, FWI faces many challenges, which include:

- The classical full waveform inversion in the data space.

- Full waveform inversion in the image space.

- Finite frequency traveltime tomography and smooth kernels.

- Acoustic, elastic, anisotropic inversions and the role of density.

- Regularization, and a priori and posterior distributions.

- Diving waves versus reflection events.

- Modeling speed up and accuracy for velocity inversion.

- The role of Multiples (Good or bad).

- Full waveform inversion applications: high resolution, unconventionals, microseismic.

The objective of this workshop is to discuss the challenges and difficulties in full waveform inversion for applications in resolving the near surface, as well as, land data and offshore subsalt.
