Often acoustic impedance can be related to porosity.It can be diÂrectly compared to well log measurements and allows a physically motivated link to reservoir properties. Acoustic impedance is a physical rock property.Hence enhanced resolution of the sub-surface layers. Reduction of wavelet effects, tuning and side lobes.Typically stratigraphic interpretation is easier on impedance data.
Acoustic impedance is a layer property, whereas seismic data is an interface property.Seismic inversion offers several benefits : The resulting impedance volume can be used to predict reservoir properties away from well control. Post-stack inversion transforms a single seismic data volume into acoustic impedance through integration of the seismic data, well data and a basic stratigraphic interpretation.
