Seismic data from West Africa has been known for some time to be significantly influenced by seismic P-wave anisotropy. Historically, these effects have been handled by seismic processing and interpretation through a series of correction factors. More recently, the industry has turned to a more theoretically correct set of processing methods. The seismic data from West Africa are estimated using this method considering the anisotropy in its simplest form, transverse isotropy with a vertical axis of symmetry.
