Abstract
A09 RESERVOIR DELINEATION USING JOINT PRESTACK INVERSION OF MULTICOMPONENT SEISMIC DATA 1 Introduction Lithological and pore fluid properties can be inverted from prestack seismic data for reservoir characterization with the use of amplitude versus offset (AVO) analysis. When the P-wave contrast is small or gas clouds obscure reservoir layers multicomponent sea bottom recording of converted waves (Ps) is used to map reservoir zones. Angle band stacks of multicomponent P-wave (Pz) and Ps data inverted jointly provide absolute acoustic impedance (AI) S impedance (SI) and density. These computations can be used to map reservoir parameters through all stages of field development
