The EAGE and PESGB have joined forces to establish a series of workshops to address this and other issues involved in velocities. In this second workshop, the focus is on all aspects of reducing uncertainties; including applications in seismic imaging, velocity model building, pore pressure prediction, depth conversion, and drilling.

There will be four presentations by PGS:

• Use of a robust norm in reducing FWI uncertainty in the presence of cycle skipping - J. Ramos-Martinez, A. A. Valenciano, N. Chemingui and T. Martin
• Sample size automation in a pseudo-random model uncertainty workflow - T. Martin
• Integrating FWI models and broadband data for elastic property generation, what is appropriate? - T. Martin, C. Reiser
• Deep updates - challenges and solutions for FWI - N. Chemingui, A. A. Valenciano and T. Martin
