The Relationship between Lamé’s Constants, 2 and µ, and the Fluid Factor in AVO Analysis of Seismic Data

Description of Lamé’s Constants<br>The idea of using Lamé’s constants in AVO analysis was first propounded by Goodway et al<br>(1997). Lamé’s constants are elastic moduli which have been found useful in the description of the elastic<br>behaviour of materials. The modulus p is the shear modulus or rigidity, but .... is generally held to<br>have no physical meaning, being a parameter substituted into equations describing elastic<br>behaviour to make them simpler.
