Improved Low Frequency Model Building for Seismic Inversion

F006 IMPROVED LOW FREQUENCY MODEL BUILDING FOR SEISMIC INVERSION R. VAN BOOM* V. BETZLER EAGE 67th Conference & Exhibition — Madrid Spain 13 - 16 June 2005 1 Wintershall Noordzee B.V. Eisenhowerlaan 142 2508 EH The Hague The Netherlands Abstract Seismic inversion to acoustic impedance can only be useful for exploration purposes if the low frequency part can be adequately modeled. In areas of limited velocity information regional information can be extrapolated into the area under investigation to build a more reliable model needed for inversion. We present a way for improving the low frequency model by taking into account
