KRYLOV-SPACE-BASED QUASI-NEWTON PRECONDITIONER FOR FULL WAVEFIELD INVERSION |
摘要 |
A method, including: storing, in a computer memory, seismic data acquired from a seismic survey of a subsurface region; and generating, with a computer, a final subsurface physical property model of the subsurface region by processing the seismic data with an iterative full wavefield inversion method, wherein the iterative full wavefield inversion method generates the final subsurface physical property model by iteratively applying a linear solver with a preconditioner that is generated from information from one or more previous iterations of the linear solver. |
