Weak-anisotropy moveout approximations for P-waves in homogeneous layers of monoclinic or higher anisotropy symmetries
Original language description
We have used so-called weak anisotropy (WA) parameteriza- tion as an alternative to the parameterization of generally aniso- tropic media by a stiffness tensor. WA parameters consist of linear combinations of normalized stiffness-tensor elements controlling various seismic signatures; hence, they are theoreti- cally extractable from seismic data. They are dimensionless and can be designed to have the same order of magnitude. WA parameters, similarly to Thomsen-type parameters, have a clear physical interpretation. They are, however, applicable to anisotropy of any symmetry, strength, and orientation. They are defined in coordinate systems independent of the symmetry elements of the studied media. Expressions using WA parame- ters naturally simplify as the anisotropy becomes weaker or as the anisotropy symmetry increases. We expect that, due to these useful properties, WA parameterization can potentially provide a framework for seismic data processing in generally anisotropic media. Using the WA parameterization, we have derived and tested approximate P-wave moveout formulas for a homo- geneous layer of up-to-monoclinic symmetry, underlain by a horizontal reflector coinciding with a symmetry plane. The de- rived traveltime formulas represent an expansion of the travel- time with respect to (small) WA parameters.
