Abstract:
Full-waveform inversion (FWI) uses the complete seismic wavefield (transmitted, reflected and converted waves) to build the models of subsurface physical properties. We conducted a feasibility study of a 2D elastic FWI applied to the synthetic and field single offset vertical seismic profile (VSP) datasets. A good correlation is demonstrated between VSP migration image, FWI results, gamma-ray log and stratigraphy even though the ray coverage is limited for a single offset VSP and numerous artefacts are observed in the images built by using FWI. The described approach allowed imaging of a subsurface, identification of geological contacts and their shapes.
