I'm now working as a processing geophysicist in CGG.
I am working in a depth imaging department,
- on applications of full waveform inversion (North Sea, Asia)
- on Q-tomography by extracting the amplitude from migrated gathers along specific horizons
- on slope tomography based on the minimization of the RMO.
I terminated my PhD in 2012, that is entitled: 'Seismic imaging of 2D visco-elastic media by stereotomography and Full Waveform Inversion (FWI): application to the Valhall oil / gas field in North Sea'. The full waveform inversion attempts to build quantitative high-resolution images of the subsurface physical parameters using the full wavefield, solved as an optimization procedure. In this thesis, I present application of two-dimensional frequency-domain full waveform inversion for imaging visco-elastic parameters from large offsets data.
