Abstract
Much AVO (Amplitude versus Offset) analysis involves linearised inversion of simplified Zoeppritz equations (Smith and Gidlow, 1987) . The approximations are only valid for small changes of physical properties, and for angles of incidence significantly leas than critical. Therefore, weighted stack AVO analysis is only applicable over a restricted range of conditions .
