  • Methods and systems for seismic inversion and related seismic data processing
    Patent number: 10353099
    Abstract: A method and system of processing seismic data is presented. The method may include, for each of a plurality of seismic traces, generating a respective intermediate set of reflectivity coefficients and a partial deconvolution of an estimated wavelet from the respective seismic trace. The method may also include decomposing a model into a plurality of orthogonal components, and projecting each of a plurality of eigenvectors corresponding to one of the orthogonal components onto intermediate reflectivity coefficients corresponding with all of the plurality of seismic traces at each of a plurality of times to generate a plurality of eigen-coefficients associated with each of the plurality of times. The eigen-coefficients may be used to generate a plurality of basis coefficients, which may then be used to generate a respective updated set of reflectivity coefficients for each of the seismic traces.
