Title: Salt Geometry Reconstruction In Seismic Imaging
Full-Waveform Inversion attempts to estimate a high-resolution model of the Earth by inverting all the seismic data. This procedure fails if the Earth model contains high-contrast bodies such as salt. These bodies are important for hydrocarbon exploration. We propose a parametric level-set method to estimate these geometries by incorporating prior information about their properties. Tests on a suite of idealized salt geometries show that the proposed method is stable against a modest amount of noise.
Speaker Bio: Ajinkya Kadu is a Ph.D. student at Mathematical Institute of Utrecht University in The Netherlands. He completed his bachelor's and master's degrees from Department of Aerospace Engineering at Indian Institute of Technology, Bombay in 2015. For his Ph.D., he's working with Tristan van Leeuwen and Wim Mulder to develop mathematical methods for inverse scattering problem. His Ph.D. is supported by Netherlands Organization for Scientific Research (NWO) and Royal Dutch Shell.
