Optimal Transport Full Waveform Inversion - Applications

Abstract

In this abstract, we present and analyze a set of land and marine applications. Firstly, a marine application on the Greater Castberg area, with a source over the streamer acquisition configuration. The comparison to the conventional LS-FWI results shows the mitigation of cycle skipping brought by multiD OT-FWI. Secondly, a land application on complex fault structures on-shore Oman, where we show that multiD OT-FWI can improve the delineation of complex velocity structures even below the maximum penetration depth of diving waves. The last example is a second land application from Oman, in an area proven to be particularly challenging for imaging, and even more for FWI (Perez-Solano and Plessix, 2019). It shows how multiD OT-FWI can be used jointly with a Multi-Wave Inversion (MWI), to better characterize the near surface.
