Patents by Inventor Leonardo QUEVEDO

Leonardo QUEVEDO has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Methods and devices using effective elastic parameter values for anisotropic media
    Patent number: 11828895
    Abstract: Methods and devices for seismic exploration of an underground formation including an orthorhombic anisotropic medium or a tilted transverse isotropic medium are provided. Isotropic-type processing techniques use effective elastic parameter values calculated based on elastic parameter values, anisotropy parameter values and azimuth angle values for the orthorhombic anisotropic medium. For the tilted transverse isotropic medium, the effective elastic parameter values depend also on the tilt angle thereof.
    Type: Grant
    Filed: August 5, 2019
    Date of Patent: November 28, 2023
    Assignee: GEOSOFTWARE C.V.
    Inventors: Catalin Tanase, Leonardo Quevedo, Peter Mesdag, Harry Debeye
  • Method and apparatus for unambiguously estimating seismic anisotropy parameters
    Patent number: 11243318
    Abstract: The orientation of the symmetry axis of an underground formation including an HTI layer is determined by comparing azimuthal Fourier coefficient of inversion results in distinct source-receiver azimuth ranges with values expected from the HTI assumption. A branch-stacking technique or prior knowledge may be used to select one of the anisotropy axis orientation values.
