To investigate seismic data acquisition, processing and interpretation in order to improve the three dimensional imaging and characterization of the subsurface.
The proposed project includes two complementary approaches.
1) A new generation of seismic physical models using laser technologies which would allow complete 3D modelling and 3-component recording and from a more global point of view more reliable simulations of seismic prospecting experiment in the laboratory. The work programme of this sub-project includes three tasks:
(i) the finalization of a broad frequency band laser interferometer point receiver allowing 3D vibration recording,
(ii) the finalization of a broad frequency band point source,
(iii) the performance of propagation experiments, first on simple models allowing the comparison with numerical methods and then with more sophisticated media of propagation.
2) A linearized elastic inversion method of prestack reflected waves for nearly horizontal layers but with possible lateral variations of the elastic parameters. The work program of this sub-project includes four tasks:
(i) the analysis and the implementation of a linearized elastic inversion method of pre-stacked reflected waves for horizontal reference media,
(ii) the analysis and the implementation of a linearized elastic inversion method of pre-stack reflected waves for smoothly varying reference media,
(iii) the analysis of the a priori information and evaluation of its impact in the outcome of the inversion procedures,
(iv) the tests on synthetic and field data.
