  • System and method for ray based tomography guided by waveform inversion
    Patent number: 9857489
    Abstract: Disclosed herein is a system and method for building a velocity model for a geographical area of interest (GAI). The system and method comprise determining a ray based tomography velocity image of said GAI using acquired data, determining a high resolution velocity guide (HRVG) image of said GAI, scaling said determined HRVG of said GAI, adding the scaled HRVG to the ray based tomography velocity image to determine an updated ray based tomography velocity image, and determining whether said updated ray based tomography velocity image has experienced convergence by determining whether a cost function of said ray based tomography velocity image does not improve compared to a previously determined cost function value of said ray based tomography velocity image.
    Type: Grant
