Three study cases were used to evaluate the influence of broadband seismic data in inversion studies. In the first case, seismic data recorded in the Hussar Experiment showed the advantage of preserving the low-frequency component from acquisition through data processing. Processing performed on data from the Project Pioneer, proved the importance of taking special care of noise attenuation processes. The radial filter demonstrated to be useful in supressing coherent noise while retaining low-frequency signal. In both cases, lateral variation in the inversion results are associated to the presence of low-frequency signal in the seismic data suggesting that the seismic reflections are controlling the impedance response. In the third study, 2D seismic modelling was performed to simulate the CO2 injection scenario in the Nisku Formation in the Wabamun area. A decrease in the impedance values of ~7% is observed in the post-injection scenario and the identification of the CO2 plume is more evident in the inverted result than in stacked section.
