Effective Biot theory and its generalization to poroviscoelastic models

X Liu, S Greenhalgh, B Zhou… - Geophysical Journal …, 2018 - academic.oup.com
A method is suggested to express the effective bulk modulus of the solid frame of a
poroelastic material as a function of the saturated bulk modulus. This method enables
effective Biot theory to be described through the use of seismic dispersion measurements or
other models developed for the effective saturated bulk modulus. The effective Biot theory is
generalized to a poroviscoelastic model of which the moduli are represented by the
relaxation functions of the generalized fractional Zener model. The latter covers the general …
