  • 3D Elastic Full Waveform Inversion - On Land Study case 

    Kormann, Jean; Marti, David; Rodríguez, Juan E.; Marzan, Ignacio; Gutiérrez, Natalia; Ferrer, Miguel; Hanzich, Mauricio; de la Puente, Josep; Carbonell, Ramon; Cela, Jose M.; Fernández, S. (European Association of Geoscientists and Engineers, 2016-05-31)
    Conference report
    Open Access
    Full Waveform Inversion is one of the most advanced processing methods that is recently reaching a mature state after years of solving theoretical and technical issues such as the non-uniqueness of the solution and harnessing ...
  • 3D Viscoelastic Anisotropic Seismic Modeling with High-Order Mimetic Finite Differences 

    Ferrer, Miguel; de la Puente, Josep; Farrés, Albert; Castillo, José E. (Springer, 2015)
    Part of book or chapter of book
    Open Access
    We present a scheme to solve three-dimensional viscoelastic anisotropic wave propagation on structured staggered grids. The scheme uses a fully-staggered grid (FSG) or Lebedev grid (Lebedev, J Sov Comput Math Math Phys ...
  • Acceleration strategies for elastic full waveform inversion workflows in 2D and 3D 

    Kormann, Jean; Rodríguez, Juan E.; Ferrer, Miguel; Farrés, Albert; Gutiérrez, Natalia; de la Puente, Josep; Hanzich, Mauricio; Cela, José M. (Springer International Publishing, 2017-02-01)
    Article
    Open Access
    Full waveform inversion (FWI) is one of the most challenging procedures to obtain quantitative information of the subsurface. For elastic inversions, when both compressional and shear velocities have to be inverted, the ...
  • Elastic Full Waveform Inversion (FWI) of reflection data with a phase misfit function 

    Kormann, Jean; Rodríguez, Juan E.; Ferrer, Miguel; Gutiérrez, Natalia; de la Puente, Josep; Hanzich, Mauricio; Cela, José M. (Springer International Publishing, 2016-04-08)
    Part of book or chapter of book
    Open Access
    Full Waveform Inversion of elastic dataset is challenging due to the complexity introduced by free-surface effects or P-S wave conversions among others. In this context, large offsets are preferred for inversion because ...
  • Mimetic Operators for Seismic Exploration 

    de la Puente, Josep; Rojas, Otilio; Ferrer, Miguel; Kormann, Jean (European Association of Geoscientists and Engineers, 2016-05-31)
    Conference report
    Open Access
    Mimetic operators are a kind of discrete operators which, on staggered grids, can accomplish "mimetic" properties analogous to their continuous counterparts. Furthermore, they can attain identical convergence order everywhere ...
  • Toward an automatic full-wave inversion: Synthetic study cases 

    Kormann, Jean; Rodriguez, Juan E.; Gutiérrez, Natalia; Ferrer, Miguel; Rojas, Otilio; de la Puente, Josep; Hanzich, Mauricio; Cela, Jose M. (Society of Exploration Geophysicists, 2016-12)
    Article
    Open Access
    Full-waveform inversion (FWI) in seismic scenarios continues to be a complex procedure for subsurface imaging that might require extensive human interaction in terms of model setup, constraints, and data preconditioning. ...
