Estimation of Lame's parameters from P-waves in a VTI medium

In this paper, we introduce a formula for extracting Lame's parameters (λ and μ) in a VTI medium. We show the application of the inversion method to this formula for extracting reflection coefficients of P- and S-wave velocities in a VTI medium. Finally, we show the application of this method to a carbonate reservoir in South West Iran. Results of this research indicate that, if anisotropy parameters are used in steps while extracting λ and μ, we can distinguish between reservoir zones with different lithology and fluid content
