Popis: | Summary In this work we investigate the effects of VTI anisotropy in the AVA response of a sand class IIp reservoir offshore West Africa. We performed synthetic modeling based on isotropic and anisotropic approaches and compared the results with pre-stack seismic gathers to understand the angle-dependent effects of VTI anisotropy. We also compared the seismic-well ties when an anisotropic reflectivity model was taken into account with respect to the conventional well-tie where anisotropy is neglected and isotropic Zoeppritz equations are used. |
