Title: Salt Geometry Reconstruction In Seismic Imaging

Abstract:
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.
