Abstract
Fractures exist on a wide range of scales from microns to hundreds of meters. Throughout this scale range, fractures have a significant influence on fluid flow and physical properties of rocks. The average elastic properties of a randomly fractured fluid-filled rock were discussed for different fracture distribution laws in association with the extremely slow and dispersive guided wave propagation within individual fractures. Krauklis wave was used as an asymptotic solution of the fluid interface wave (FIW) equations. Different fracture distribution laws (exponential, power, fractal and gamma laws) within the rock in the seismic range of frequencies (
