Cross-well Seismic Constrained Acoustic Impedance Inversion

Seismic traces obtained from cross-well reflection imaging and well log data are used in the multi well log restriction random inverse acoustic impedance inversion.First the cross-well reflection(imaged) data was inverted to obtain an acoustic impedance profile.Then some acoustic impedance traces (extracted) from the inversion profile were used as virtual log and combined with well log data to implement the cross-well and surface seismic joint inversion.The modeling and filed data inversion results shown that cross-well and surface seismic joint inversion can provide more restriction in the surface seismic(inversion) and can improve accuracy of inversion.
