Low frequency seismic data down to 2/3 Hz is required if seismic inversion to absolute rock and reservoir properties is aimed. Presently about 3/4 Hz offshore and 4/5 Hz land seismic data are feasible using specially arranged receiver and source arrays. The missing low frequencies in these cases can be obtained using background models derived from the seismic interval velocity field without having to rely on models from well log data. Seismic bandwidth extending to high frequencies is also important in getting reliable rock and reservoir property estimations from seismic data. Influence of low and high frequencies in seismic inversion are illustrated with synthetic and field data.
