Introduction
-
We extend the results presented in paper by Bucha (2013c) who
rotated the tensor of elastic moduli around the axis
x2 only. The extension includes rotations
around axes x1 and x3.
-
We demonstrate the impact of
rotation of the tensor of elastic moduli
on migrated images.
-
The dimensions of the velocity model, shot-receiver configuration,
methods for calculation of the recorded wave field and the migration
are the same as in previous papers by Bucha (2011, 2012a, 2012b,
2013a, 2013b, 2013c).
-
The recorded wave field is generated
in simple models composed of
two homogeneous layers separated by a non-inclined
curved interface.
The anisotropy of the upper layer is orthorhombic
with the rotation of the tensor of elastic moduli
around axes
x1, x2 or x3.
-
We apply the ray-based Kirchhoff prestack depth
migration to
single-layer velocity models with orthorhombic anisotropy
with and without
the rotation of the tensor of elastic moduli.
-
We show and discuss errors of the migrated interface caused by
incorrect
velocity models used for migration.
