Abstract
The exact expression for the P-P reflection coefficient (Zoeppritz equations) has a rather complicated dependence on the medium parameters (P- and S-wave velocities and density) at both sides of the interface. For the inversion purpose, it’s required approximations formulas. In this work we discuss some approximations based on Taylor series and on the impedance concept. We also present the inversion process induced by these approximations.
