SYSTEM AND METHOD FOR DISPLAYING SEISMIC DATA Russian patent published in 2016 - IPC G01V1/28 

FIELD: data processing.

SUBSTANCE: disclosed is a method for displaying seismic data, including approximation of coefficients of inclined transverse-isotropic medium (TTI) with application of Pade approximation and disperse equation. Method involves the use of hybrid one-sided wave migration in inclined transverse-isotropic medium (TTI-WEM) to high-speed model and parameters of anisotropy for non-summarised accelerogram of a common source point (CSP) using approximated coefficients of TTI and a computer system to determine the value of propagation of the wave field from the side of the source and values of propagation of the wave field from the side of the receiver in the spatial frequency domain. One performs conversion of the the values of the wave field propagation from the side of the source and the values of the wave field from the side of the receiver from spatial-frequency domain into spatial-time domain. Use is made of equations for cross-correlated display with a zero delay to form a partial output display using the converted value of the wave field propagation from the side of the source and the converted value of the wave field propagation from the side of the receiver. Also disclosed is a data carrier.

EFFECT: high accuracy and reliability of obtained data.
