Whilst the equa- tions and software implementations are straightforward, there are potential pitfalls. Several authors have noted

A direct result of Gassmann's equations is that the shear modulus for an isotropic material is independent of pore fluid, and therefore remains constant during the fluid substitution process.

Gassmann's equation – a fluid substitution tutorial. Author: Supervisor: Nawras Al-Khateb Dr. Laurence R. Lines. Table of Contents. Abstract. Gassmann's equation is commonly used to perform fluid substitutions and predict velocity changes resulting from different pore-fluid saturations, which is an important part of seismic

Fluid substitution is an important part of seismic attribute work, because it provides the interpreter with a tool for modeling and quantifying the various fluid scenarios which might give rise to an observed amplitude variation with offset (AVO) or 4D response.
