Anisotropy
Effects of Shale/Sand Anisotropy on AVO-Based Reservoir Characterisation
Intrinsic shale anisotropy in combination with often present
stress induced reservoir sand anisotropy presents a challenging
situation for reservoir characterisation from seismic data.
Research in this area includes analysis of the magnitude of
anisotropy, separation of the sand from shale anisotropy
contribution to AVO signature and fracture characterisation from
borehole and surface seismic measurements.

Fracture Orientation from Anisotropy Measurements
Methods of finding orientation of symmetry axes of the
medium from its elasticity parameters have been developed.
Knowledge of the symmetry axes can aid in finding the
orientation of fractures in the medium. However, the
measurements of the elasticity parameters in seismology is prone
to large errors. The scope of the current research is to adapt
the developed methods to deal with these errors.
