Implicit Finite‐Difference Plane Wave Migration in TTI Media

Abstract: Implicit finite-difference (IFD) extrapolation operator and plane wave migration in TTI media are studied in this paper. Compared to isotropic and VTI media, the dispersion relation of TTI media is much more complicated. It is difficult to get the explicit expression of the dispersion relations. It needs no longer only a symmetrical even function like isotropic and VTI media but also an odd function to express the dispersion relations. We design TTI medium IFD wave-field extrapolation operator and solve operat… Show more

“…The method of operators as a tool for the investigation of the solution to stochastic parabolic equations in Hilbert and Banach spaces has been systematically developed by several authors (see and the references therein). Finite difference method for the solution of initial boundary value problem for stochastic partial differential equations has been studied extensively by many researchers (see and the references therein). However, initial boundary value problems for stochastic hyperbolic differential equations were not well investigated.…”

“…For example, the method of operators as a tool for investigation of the solution to stochastic equations in Hilbert and Banach spaces have been used systematically by several authors see, 1-7 and the references therein . Numerical methods and theory of solutions of initial boundary value problem for stochastic partial differential equations have been studied in [8][9][10][11][12][13][14][15][16] . Moreover, the authors of 17 presented a two-step difference scheme for the numerical solution of the following initial value problem: dv t −Av t dt f t dw t , 0 < t < T, v 0 0,v 0 0, 1.1 for stochastic hyperbolic differential equations.…”
