L-32 THE EFFECT OF SEISMIC ANISOTROPY ON MULTICOMPONENT IMAGING AND AVO Summary 1 This paper shows how seismic anisotropy affects the imaging and AVO of multicomponent seabed data acquired over the Siri reservoir in the North Sea. Model-based processing is used to analyze the data and compare results from isotropic and anisotropic velocity models. A layered vertically transversely isotropic (VTI) model was used in this study constructed by Grechka et al. (2001). Neglecting the overburden anisotropy causes 0−550 m smearing of the reflection points of converted PS-waves at the target level and results in false PS AVO. Such smearing greatly
