Full Waveform Inversion: Land and Shallow Water Challenges


10–12 October 2023
Abu Dhabi, UAE

Workshop Description

While FWI has recently made giant strides in deep water subsurface imaging, the technology is lagging significantly for land and shallow water applications. Noise — whether ambient or source related — is clearly an issue, especially for the low frequencies that are so critical for successful implementation. Perhaps more problematic is the need to construct an accurate high-resolution model of the near surface. Depending on the terrain, the near surface can have large velocity contrasts, high anisotropy, high attenuation, significant heterogeneities leading to scattering, and strong multiple generators. A proper model of the near surface might need to be possibly viscoelastic and require a fine computational grid to handle the ultra-low elastic velocities we encounter in the near-surface, which may be a challenge for today’s computer capacity. To make matters worse, the near surface is often ill-sampled by cost effective 3D acquisition designs.

Despite all these hurdles we are starting to see some beneficial FWI applications to land and shallow water surveys. How important are data conditioning, wavelet estimation and the choice of the initial model? Do we have to move to elastic FWI? Can ground roll, mud roll and multiples help rather than hinder the process? Do we need to design our surveys differently? Can we use other complementary data? What do we do with all the scattering noise? What is the role of Machine Learning? Is there room for improvement in acquisition? The goal of this workshop is to review the state-of-the art and investigate the next key steps to address some of these questions.

The workshop focuses on the current challenges of FWI on land and shallow water seismic data and the technological advances and improved workflows that aim to resolve subsurface complexities (both near-surface and deep), and complex structures and their collective impact on FWI. In addition, the workshop will address novel acquisition and processing methods, and the application of machine learning in FWI. Case studies in both land and shallow water regimes will be presented and innovative borehole applications of FWI will also be introduced.

Workshop attendees will have the opportunity to appraise the latest advancements in the application of FWI on land and shallow water surveys and industry progress on the path to elastic FWI. All those interested in applying FWI to seismic data should attend. Managers will recognize the important role of FWI in the future of seismic imaging. Processing geophysicists will gain a broader understanding of both the challenges hindering successful deployment of FWI on land and shallow water data, as well as the latest approaches to resolving these challenges. Similarly, borehole geophysicists will gain insights into the role of FWI in advancing borehole geophysics.

We anticipate broad engagement from both academia and industry, from the Middle East and further afield. Our underlying objective is to facilitate a platform for advancing FWI in land and shallow water surveys within a technical community that shares the common goal of resolving the aforementioned challenges and progressing toward the ultimate goal of elastic FWI.
