Generalized Non-Hyperbolic Moveout Approximation

B041 Generalized Non-Hyperbolic Moveout Approximation S.B. Fomel* (University of Texas at Austin) & A.M. Stovas (NTNU) SUMMARY We propose a general functional form for nonhyperbolic moveout approximations that can be applied to any kind of seismic media. The proposed form includes five coefficients as opposed to two coefficients in the classic hyperbolic approximation. In certain cases the number of coefficients can be reduced. In the general case determining the optimal coefficients requires tracing of only one non-zero-offset ray. Using analytical ray tracing solutions and numerical experiments we compare the accuracy of our approximation with the accuracy of other known approximations
