This E-Lecture: "Improved Rock Property Estimation from Joint Inversion of PP and PS Reflectivities". The objective of this work was to develop a method for joint inversion of PP and PS data with the goal of unique and accurate determination of important layer parameters, namely y1 and y2 ratios. The method also gives reliable estimates of density ratio, a parameter that can be directly linked to hydrocarbon saturations. The usage of the method is limited to the assumptions used in the derivation of Zoeppritz’s equations, i.e. interface of two horizontal, homogeneous, isotropic, elastic layers. What is new? Easy to understand approach for inversion of all four elastic parameters entering Zoeppritz equations.
