Change in Effective Elastic Properties of Solid-Filled Porous Media upon Substitution
Biot-Gassmann relations that link the change in effective elastic properties of fluid-filled porous media to the change in pore fluid properties are not applicable for solid-filled porous media. Such problems arise when concerned with pore-filling materials with non-negligible shear modulus; examples of such materials include molten lava, cold bitumen, kerogen, clay, etc. In this paper, we discuss how effective solid-filled bulk and shear moduli of a solid-filled porous medium (or composite) are explicitly related to other effective stiffnesses and pore-filling solid elastic properties. Such relations are known as substitution equations and are particularly useful in exploration geophysics, for example in reservoir monitoring. We present new equations which improve on previously suggested solid substitution relations by Ciz and Shapiro.
