Generalized nonhyperbolic moveout approximation |

According to the acoustic approximation of
Alkhalifah (1998), one can use the following parametric
equations to define the traveltime-offset relationship in a
homogeneous VTI model:

where is the ray parameter, is the depth of the reflector, is the vertical velocity, is the NMO velocity, and is the dimensionless parameter introduced by Alkhalifah and Tsvankin (1995).

At small offsets, the homogeneous VTI traveltime behaves as

At large offsets, the homogeneous VTI traveltime behaves as
