A geo-imaging challenge: Combine deterministic seismic inversion, machine learning and geologic prior knowledge to arrive at beyond-wavelength resolution of fine-scaled subsurface structures
The seismic method has been used for several application fields of subsurface exploration and monitoring. The resolution of the final subsurface information is traditionally limited by the local wavelength in the medium. In addition, traditional target area inversion for the elastic parameters is based on local 1.5D assumptions of the layering. In many cases the subsurface structures have a multi-dimensional character with complex depositional structures. But in case prior knowledge is available about possible fine-scaled local stratigraphic architectures of the subsurface structures and using Machine Learning to link this information to the observed seismic data signatures, we aim at inverting seismic data beyond traditional resolution.
This proposed PhD project is a duo-project with a geologic counterpart, in which all relevant geologic scenario information is generated. Thus, the proposed project has a strong emphasis on wave theory, seismic imaging and inversion and Machine Learning. It is within the context of a large industry-sponsored geo-imaging project Delphi (that is mostly executed within Delft University of Technology.
Research in the department of Imaging Physics is aimed at developing novel instrumentation and methodology in imaging science and sensing technology. Our research products extend existing boundaries in terms of spatial resolution, temporal resolution and information/data throughput. We are pioneers in developing advanced concepts of computational imaging, a marriage between cleverly designed imaging systems and sophisticated post-processing. In everything we do, there is a core of cutting edge physics and engineering of high-tech instruments, of the use of the most advanced computing techniques, and of a very close link to real-life applications. Our work has clear societal impact in the areas of life sciences, healthcare, and industry.
