Abstract:
Gassmann fluid substitution is widely used in geophysical practice. In the last few years, the topic of fluid/solid substitution has emerged, where the substances filling the pore space can be solids, fluids, or visco-elastic materials, such as heavy oils. Solid substitution cannot be accomplished with the Gassmann theory because the finite rigidity of the pore fill (either solid or viscoelastic) prevents pressure communication throughout the pore space, which is a key assumption of the Gassmann theory.In this paper we explore applicability of solid substitution techniques by using a sandstone saturated with a solid substance, octodecane.
