Latest Patents
One of his latest patents is titled "Fourier finite-difference migration for three-dimensional tilted transverse isotropic media." This method focuses on migrating three-dimensional seismic data in tilted transversely isotropic media (TTI). It involves generating numerical solutions to an exact relationship for a three-dimensional dispersion relationship of seismic energy traveling through TTI media. The process utilizes selected input values of polar angle and azimuth angle of a transverse isotropic axis of symmetry, along with Thomsen anisotropic parameters, to create tables of numerical values. These values are then used to estimate optimized coefficients for a finite-difference relationship along multiple splitting directions, ultimately migrating the seismic data using a three-dimensional Fourier finite difference extrapolation algorithm.
Another significant patent is the "Method for building velocity models for imaging in multi-azimuth marine seismic surveys." This innovative approach employs a programmable computer to migrate 3D seismic data sets corresponding to each azimuth in seismic data obtained from multi-azimuth marine seismic surveys. The acquisition geometry is stored for each trace, and residual analysis is performed on the migrated data sets. The generated residuals and reflectors are then rotated and merged on a master grid, applying reflection tomographic inversion iteratively to update a velocity model. This updated model is crucial for imaging the earth's subsurface accurately.
