Details

Researchers, practitioners, students, and decision makers interested in better understanding the value and challenges of elastic FWI. With the constant increase of HPC capabilities, elastic FWI has rapidly progressed over the last decade and is today used at an industrial scale. Elastic FWI, however, covers different levels of complexity: from modeling and inverting the P waves elastically with a mono-parameter inversion to modeling and inverting in a multi-parameter inversion scheme waveforms considered as coherent noise in classical acoustic processing flows (mode conversions, surface waves, …). The complexity level, and then computing cost, depend on the objective to achieve and the type of seismic acquisitions considered (land or marine acquisitions). During this workshop, we propose to focus on assessing the added value of elastic versus acoustic FWI in terms of velocity model building and imaging for on-shore and off-shore data.
