3-D AVO MIGRATION INVERSION OF FIELD DATA

3-D AVO migration/inversion is applied to data from the Oseberg field in the Norwegian sector of the North Sea. The objectives of this study were to consider the feasibility of AVO migration/inversion in 3-D, p rototype the codes, and develop a preliminary 3-D methodology. All of these objectives have been satisfactorily achieved. Interpretation of the results show that AVO migration/inversion yields accurate litholog y and fluid information and allows identification of new faults in the reservoir zone.
