... in Figure 1, the proposed approximations of the Zoeppritz equations (Aki and Richards, 1980; Shuey, 1985) are appropriate only in the cases of small incidence angles in the PP domain, while in the PS domain, the error of approximation is too large to be ignored. As a result, the reservoir models cannot...
