Elastic wave mode separation for TTI media
The separation of wave modes for isotropic elastic wavefields is typically done using Helmholtz decomposition. However, Helmholtz decomposition using conventional divergence and curl operators is not satisfactory for anisotropic media and leaves the different wave modes only partially separated. The separation of anisotropic wavefields requires more sophisticated operators which depend on local...

The separation of wave-modes for isotropic elastic wavefields is typically done using Helmholtz decomposition. However, Helmholtz decomposition using conventional divergence and curl operators in anisotropic media only partially separates the elastic wave-modes. The separation of anisotropic wavefields requires operators which depend on local material parameters. Wavefield separation operators ...
متن کاملElastic wave-mode separation for VTI media
Elastic wave propagation in anisotropic media is well represented by elastic wave equations. Modeling based on elastic wave equations characterizes both kinematics and dynamics correctly. However, because P and S modes are both propagated using elastic wave equations, there is a need to separate P and S modes to obtain clean elastic images. The separation of wave modes to P and S from isotropic...
متن کاملElastic wave mode separation for tilted transverse isotropic media
Seismic waves propagate through the earth as a superposition of different wave modes. Seismic imaging in areas characterized by complex geology requires techniques based on accurate reconstruction of the seismic wavefields. A crucial component of the methods in this category, collectively known as wave-equation migration, is the imaging condition that extracts information about the discontinuit...
متن کاملlastic wave - mode separation for VTI media
Elastic wave propagation in anisotropic media is well represented by elastic wave equations. Modeling based on elastic wave equations characterizes both kinematics and dynamics correctly. However, because Pand S-modes are both propagated using elastic wave equations, there is a need to separate Pand S-modes to efficiently apply single-mode processing tools. In isotropic media, wave modes are us...
