Shear-wave anisotropy results in a time delay between two different shear-wave polarizations S1 and S2. If there are associated differences in attenuation of the amplitudes, then simple time shifting is insufficient to match the S1 and S2 images. This ―differential‖ attenuation leads to both an additional time delay and a frequency dependent amplitude effect. Using a dataset acquired over a heavy oil reservoir, we demonstrate that an improvement to the agreement between P-S1 and P-S2 images can be achieved through the use of a match filter approach. For realistic cases, this filter must be adapted to handle spatial and temporal variations of the splitting signature. The resulting attributes suggest that further insights into the reservoir properties can be found.
