To implement the search, we Detection and measurement of shear-wave birefringence is made compute in all azimuthal directions a transfer matrix (called possible by using a propagator matrix method (Lefeuvre el the propagator matrix) which is assumed to be independent al., 1989, 1990) to process nine-component VSPs. Until now of the initial shear-wave polarization and which describes the this method was applied under a 2-D hypothesis by assuming propagation of the shear-wave in a given depth interval, This the existence of vertical fractures. Under this assumption, the transfer function is estimated by a least squares method.

Anisotropy axes are at plus 45 degrees (fast shifts are normalized in units of one period of shear-wave particle motion) and minus 45 the the dominant frequency (1 tau).
It is essential to have a focusing technique to obtain a Two current challenges in seismic imaging are to obtain detailed picture of the subsurface analogous to the focusing steps more detailed images of complex structures from reflection data of DMO and NM0 plus stack. This is when the velocity model is and to constrain the regional structure of the Earth using wideangle actually replaced by the migrated section. To do this we develop a pre-stack focusing analysis which we call MM0 (Migration data. These are complex problems for which traditional Moveout) analysis, which allows iterative updating of the methods fail because they are based on too many simplifying velocity model with very fast convergence.
As the receiver separation and an incoherent component.This decomposition decreases, these arrivals tend to become is performed by means of a local Velocity Guided coherent over a greater number of traces and Median Filter (VGMF) which acts as a coherent vice-versa.

SIRT is applicable to any data that Multiple paths between source and receiver are easily included by specifying different can be expressed as a weighted integral of initial source-to-receiver trajectories the quantity to be imaged.

F is polarized along el and e2, respectively, with signature We transform the data by four linear transform so that the F(r). The concept of the principal time series was introduced shear-wave motion is linearized in a wide variety of by Alford (1986) and Thomsen (1988). Here, we give an conditions. Many properties of shear-waves can be easily alternative geometrical definition. We introduce two estimated from the transformed components.
