Abstract

The propagation of acoustic waves in a fluid-saturated porous medium containing a continuously distributed system of fractures is discussed. The porous medium is assumed to consist of two degrees of porosity and the resulting model thus yields three types of longitudinal waves, one associated with the elastic properties of the matrix material and one each for the fluids in the pore space and the fracture space. Two approaches are considered: one based on Biot's approach utilizing the "viscodynamic operator" and one based on Aifantis' "multiporosity theory". © 1984.
