Through the support of the SEG Research Committee The goal of this workshop is to bring together technical experts to discuss the advancements in subsurface model building, imaging and FWI. The workshop aims at the current trends in the use of reflection (primary, multiples) and non-reflection modes (refractions, transmission, diffractions) in data to address the challenges in complex geological environments and possible solutions using velocity model building, imaging and FWI. Extracting detailed subsurface information has not only resulted in an increased focus in FWI, but has also accelerated research in subsurface model building including velocity, anisotropy estimation, imaging algorithms and improvements in processing workflows such as handling multiples in the data. In recent years, FWI products are commonly analyzed with conventional imaging workflows such as gather flatness and migration images and imaging workflows are increasingly incorporating FWI derived product to produce better images. Are the two paths converging to meaningful solutions to address the business needs? The workshop will address practical applications of workflows, case histories, and new developments from conventional model building, imaging improvements and FWI. The workshop will have both oral and poster session. Topical areas of interest for this workshop include: - Advances and workflow enhancements in subsurface model building and tomography
- Depth imaging in complex environments and algorithm improvements
- FWI and its applications
- Integrated case studies
- Modeling and imaging for seismic acquisition
