Work experience
- february 2015 - june 2015 : R&D Geophysicist Intern at Total AS
As part of the R&D team, my research Master thesis dealt with the feasibility
of passive seismic tomography on onshore domain by designing and developing a
workflow to retrieve the Green function from real ambient noise data and
invert for a shear wave velocity model. This work includes:
- Processing of ambient noise data: temporal normalization, spectral whitening, cross-correlation and stacking
- Beamforming analysis to study the distribution of noise
- Measuring of dispersion curves from cross-correlations using Frequency-Time analysis
- Data quality control to reject bad measurements
- Linear inversion for surface wave group velocity map at different periods
- Non-linear inversion (Markov Chains Monte Carlo) for a shear wave velocity model All the codes have been implemented from scratch in Matlab.
- march 2014 - september 2014 : R&D Geophysicist Intern at CGG Services Norway AS
As part of the Marine R&D team, my work focused on the vibration noise in 4C multicomponent
towed streamer data. My main contributions were:
- Understanding marine seismic acquisition using multicomponent sensors
- Understanding why current noise attenuation method (f-k dip filetering, f-x deconvolution, Radon transform…) failed on such noise by reviewing the pros and cons of their applications on typical noise in marine seismic data (coherent and random)
- Successfully implementing a new method to attenuate streamer vibration noise by developing an algorithm based on Singular Spectrum Analysis and defining a processing workflow I also part-time worked with the Subsurface Imaging team as a data processing geophysicist.
