Abstract
The reason why acoustic and shear impedances inverted from seismic data have become popular seismic attributes is because, unlike other attributes, they can also be easily estimated at log scale. Log-scale impedances are easier to interpret because at log scale we have additional information that provides more insight about reservoir properties, and this insight can be used to help the interpretation of seismic-scale impedances. The joint interpretation of acoustic and shear impedances estimated from seismic data can help to understand rock, fluid, and fracture variability in the reservoir.
