Anisotropic velocity models
-
The dimensions of homogeneous velocity models are the same
as in the paper by Bucha (2013a).
- The recorded wave field
is computed in velocity models composed of two layers with
-
the triclinic anisotropy representing dry Vosges sandstone
(Mensch & Rasolofosaon, 1997) without
the rotation of the tensor of elastic moduli in
the upper layer.
The bottom layer is isotropic and the P-wave velocity 3.6 km/s.
-
the triclinic anisotropy representing dry Vosges sandstone
(Mensch & Rasolofosaon, 1997) with
the rotation of the tensor of elastic moduli in
the upper layer. The angle of rotation around the
axis x2
is equal to 15 degrees.
The bottom layer is isotropic and the P-wave velocity 3.6 km/s
or 3.8 km/s.
-
The distribution of elastic moduli in each single-layer
velocity model for
the migration
is the same as the distribution
in the upper layer of the velocity model used to calculate
the corresponding recorded wave field.
