Direct Estimation of P- and S-Wave Impedance Parameters Based on Prestack Reflection Coefficients (opens in new tab)

The longitudinal and transverse wave impedance is a core parameter for describing the characteristics of reservoirs, and there is the most direct physical relationship between it and the seismic reflection coefficient. However, most of the existing impedance inversion methods rely on prior constraints such as regularization to improve the ill-posed problem, which makes the inversion process subject to many additional factors and difficult to achieve direct and stable impedance prediction. The...
