Here, we show that the zero-dip velocity and the anisotropic all parameters of TTI media responsible for kinematic parameter defined as signatures of P-waves [the symmetry-direction velocity Thornsen's (1986) anisotropic coefficients and and the tilt and azimuth of the symmetry axis] can For TI media with a horizontal symmetry axis (HTI), be obtained from azimuthally-varying P-wave the set of P-wave kinematic parameters includes the azimuth (NMO) velocities for a horizontal and a dipping of the symmetry axis, in addition to and reflector.

Here, we introduce a linearized moveout forms an ellipse in the horizontal plane. While this result correction for weak lateral velocity variation and remains valid in the presence of arbitrary anisotropy apply it to fracture detection in the Powder River Basin, and heterogeneity, the inversion of the NMO ellipse for Wyoming. Our processing sequence made it possible to the medium parameters has been discussed so far only obtain the interval NMO ellipses that carry information for horizontally homogeneous models above a horizontal about fracturing within different depth intervals.

However, the model conventionally gradient which would be recorded if interference does used to interpret AVO anamolies - a single isolated interface not exist). Wapenaar et al. (1995) showed that apparent between two isotropic half-spaces - is often too AVO behavior can be eliminated if the wave frequency simplistic. Here, I examine what can be obtained from w is considered to be such function of the horizontal AVO responses for significantly more complicated reservoir slowness that the vertical wavelength is independent model - a stack of plane azimuthally anisotropic on The result was a technique which takes the layers, the model which can be used to simulate AVO data in (to is the vertical time) domain, corrects it signatures over finely layered fractured reservoirs.
