  • Elastic full wavefield inversion with refined anisotropy and V/Vmodels
    Patent number: 11815642
    Abstract: Methods for inversion of seismic data to infer subsurface physical property parameters, comprising constructing an inhomogeneous anisotropy model and/or inhomogeneous VS/VP or VP/VS model; and inverting the seismic data in a sequential or simultaneous approach to obtain at least one subsurface physical property parameter using an elastic inversion algorithm and the inhomogeneous anisotropy model and/or inhomogeneous VS/VP or VP/VS model. Constructing an inhomogeneous anisotropy model may comprise deriving geobodies from at least one of seismic facies analysis, regional geologic information, or seismically derived earth models; and adjusting at least one of ?, ?, ?, or parameters of the elastic stiffness tensor matrix in a homogeneous anisotropy model in areas corresponding to the geobodies. Constructing an inhomogeneous VS/VP or VP/VS model may comprise deriving geobodies and adjusting values in a homogeneous VS/VP or VP/VS model in areas corresponding to the geobodies.
