Seismic inversion allows to estimate the elastic medium properties. Simultaneous seismic inversion provides a detailed model of the elastic medium properties using the results of prestack seismic data processing in the time domain. The relationship of reflection coefficients with elastic properties is given by the Zoeppritz equations. Classic simultaneous inversion approaches are based on the approximations of the Zoeppritz equations exact solution, which are valid for small contrasts of properties in the medium and for small angles of incidence of the wave. In this paper we propose an algorithm for simultaneous inversion based on the exact solution of the Zoeppritz equations. The proposed algorithm is compared with classic simultaneous inversion algorithms using realistic synthetic models.
