In this presentation, we will review the main limitations of classical FWI for imaging at depth, and the main concepts behind RWI and JFWI. Based on synthetic and real data applications on a 2D OBC datasets collected across a gas cloud, we will show the added value of such schemes and also their limitations mainly associated with the misfit function definition (cycle-skipping and amplitude dependency).
