I cannot speak to the entire discipline of Geophysics, but in the seismic world for E&P (design, acquisition, processing, interpretation, reservoir characterization) which are for your opinion the three most important problems that strike us as important?

Let me share some issues:

Rock Physics and seismic elastic inversion?

Geomechanics and anisotropy for unconventional reservoir?

Discrimination between lithology and fluid content?

Thank you very much for your answers, I will try to put a synthesis with your best knowlegde and point of view.
